  - In BIND 9.0.0 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and 9.16.8-S1 ->     9.16.13-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11 of the BIND     9.17 development branch, when a vulnerable version of named receives a query for a record triggering the     flaw described above, the named process will terminate due to a failed assertion check. The vulnerability     affects all currently maintained BIND 9 branches (9.11, 9.11-S, 9.16, 9.16-S, 9.17) as well as all other     versions of BIND 9. (CVE-2021-25215)

  - In ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16, ISC DHCP 4.4.0 -> 4.4.2 (Other branches of ISC DHCP (i.e., releases     in the 4.0.x series or lower and releases in the 4.3.x series) are beyond their End-of-Life (EOL) and no     longer supported by ISC. From inspection it is clear that the defect is also present in releases from     those series, but they have not been officially tested for the vulnerability), The outcome of encountering     the defect while reading a lease that will trigger it varies, according to: the component being affected     (i.e., dhclient or dhcpd) whether the package was built as a 32-bit or 64-bit binary whether the compiler     flag -fstack-protection-strong was used when compiling In dhclient, ISC has not successfully reproduced     the error on a 64-bit system. However, on a 32-bit system it is possible to cause dhclient to crash when     reading an improper lease, which could cause network connectivity problems for an affected system due to     the absence of a running DHCP client process. In dhcpd, when run in DHCPv4 or DHCPv6 mode: if the dhcpd     server binary was built for a 32-bit architecture AND the -fstack-protection-strong flag was specified to     the compiler, dhcpd may exit while parsing a lease file containing an objectionable lease, resulting in     lack of service to clients. Additionally, the offending lease and the lease immediately following it in     the lease database may be improperly deleted. if the dhcpd server binary was built for a 64-bit     architecture OR if the -fstack-protection-strong compiler flag was NOT specified, the crash will not     occur, but it is possible for the offending lease and the lease which immediately followed it to be     improperly deleted. (CVE-2021-25217)

  - encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write     access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character     sequence. (CVE-2021-26937)

  - An issue was discovered in GNOME GLib before 2.66.6 and 2.67.x before 2.67.3. The function g_bytes_new has     an integer overflow on 64-bit platforms due to an implicit cast from 64 bits to 32 bits. The overflow     could potentially lead to memory corruption. (CVE-2021-27219)

  - An issue was discovered in the Linux kernel through 5.10.11. PI futexes have a kernel stack use-after-free     during fault handling, allowing local users to execute code in the kernel, aka CID-34b1a1ce1458.

  - Integer overflow in the firmware for some Intel(R) Graphics Drivers for Windows * before version     26.20.100.7212 and before Linux kernel version 5.5 may allow a privileged user to potentially enable an     escalation of privilege via local access. (CVE-2020-12362)

  - Improper input validation in some Intel(R) Graphics Drivers for Windows* before version 26.20.100.7212 and     before Linux kernel version 5.5 may allow a privileged user to potentially enable a denial of service via     local access. (CVE-2020-12363)

  - Null pointer reference in some Intel(R) Graphics Drivers for Windows* before version 26.20.100.7212 and     before version Linux kernel version 5.5 may allow a privileged user to potentially enable a denial of     service via local access. (CVE-2020-12364)

  - An issue was discovered in the Linux kernel before 5.11.8. kernel/bpf/verifier.c performs undesirable out-     of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre     mitigations and obtain sensitive information from kernel memory, aka CID-f232326f6966. This affects     pointer types that do not define a ptr_limit. (CVE-2020-27170)

  - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the n_tty_receive_buf_common     function in drivers/tty/n_tty.c. (CVE-2020-8648)

  - An issue was discovered in the Linux kernel through 5.10.11. PI futexes have a kernel stack use-after-free     during fault handling, allowing local users to execute code in the kernel, aka CID-34b1a1ce1458.
    (CVE-2021-3347)

  - A flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. On a locked     down (usually due to Secure Boot) guest system running on top of PowerVM or KVM hypervisors (pseries     platform) a root like local user could use this flaw to further increase their privileges to that of a     running kernel. (CVE-2020-27777)

  - A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c.
    This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name     space (CVE-2021-22555)

  - BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements,     allowing them to execute arbitrary code within the kernel context. This affects     arch/x86/net/bpf_jit_comp.c and arch/x86/net/bpf_jit_comp32.c. (CVE-2021-29154)

  - An issue was discovered in the Linux kernel before 5.11.11. The netfilter subsystem allows attackers to     cause a denial of service (panic) because net/netfilter/x_tables.c and include/linux/netfilter/x_tables.h     lack a full memory barrier upon the assignment of a new table value, aka CID-175e476b8cdf.
    (CVE-2021-29650)

  - net/bluetooth/hci_request.c in the Linux kernel through 5.12.2 has a race condition for removal of the HCI     controller. (CVE-2021-32399)

  - Apache Tomcat 10.0.0-M1 to 10.0.6, 9.0.0.M1 to 9.0.46 and 8.5.0 to 8.5.66 did not correctly parse the HTTP     transfer-encoding request header in some circumstances leading to the possibility to request smuggling     when used with a reverse proxy. Specifically: - Tomcat incorrectly ignored the transfer encoding header if     the client declared it would only accept an HTTP/1.0 response; - Tomcat honoured the identify encoding;
    and - Tomcat did not ensure that, if present, the chunked encoding was the final encoding.
    (CVE-2021-33037)

  - A flaw was found in the Routing decision classifier in the Linux kernel's Traffic Control networking     subsystem in the way it handled changing of classification filters, leading to a use-after-free condition.
    This flaw allows unprivileged local users to escalate their privileges on the system. The highest threat     from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3715)

  - In ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16, ISC DHCP 4.4.0 -> 4.4.2 (Other branches of ISC DHCP (i.e., releases     in the 4.0.x series or lower and releases in the 4.3.x series) are beyond their End-of-Life (EOL) and no     longer supported by ISC. From inspection it is clear that the defect is also present in releases from     those series, but they have not been officially tested for the vulnerability), The outcome of encountering     the defect while reading a lease that will trigger it varies, according to: the component being affected     (i.e., dhclient or dhcpd) whether the package was built as a 32-bit or 64-bit binary whether the compiler     flag -fstack-protection-strong was used when compiling In dhclient, ISC has not successfully reproduced     the error on a 64-bit system. However, on a 32-bit system it is possible to cause dhclient to crash when     reading an improper lease, which could cause network connectivity problems for an affected system due to     the absence of a running DHCP client process. In dhcpd, when run in DHCPv4 or DHCPv6 mode: if the dhcpd     server binary was built for a 32-bit architecture AND the -fstack-protection-strong flag was specified to     the compiler, dhcpd may exit while parsing a lease file containing an objectionable lease, resulting in     lack of service to clients. Additionally, the offending lease and the lease immediately following it in     the lease database may be improperly deleted. if the dhcpd server binary was built for a 64-bit     architecture OR if the -fstack-protection-strong compiler flag was NOT specified, the crash will not     occur, but it is possible for the offending lease and the lease which immediately followed it to be     improperly deleted. (CVE-2021-25217)

  - An issue was discovered in the Linux kernel before 5.2.6. On NUMA systems, the Linux fair scheduler has a     use-after-free in show_numa_stats() because NUMA fault statistics are inappropriately freed, aka     CID-16d51a590a8c. (CVE-2019-20934)

  - In the Linux kernel before 5.6.1, drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink camera USB     driver) mishandles invalid descriptors, aka CID-a246b4d54770. (CVE-2020-11668)

  - The Linux kernel before 5.11.14 has a use-after-free in cipso_v4_genopt in net/ipv4/cipso_ipv4.c because     the CIPSO and CALIPSO refcounting for the DOI definitions is mishandled, aka CID-ad5d07f4a9cd. This leads     to writing an arbitrary value. (CVE-2021-33033)

  - In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an     hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value. (CVE-2021-33034)

  - fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer     allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an     unprivileged user, aka CID-8cae8cd89f05. (CVE-2021-33909)

  - In BIND 9.8.5 -> 9.8.8, 9.9.3 -> 9.11.29, 9.12.0 -> 9.16.13, and versions BIND 9.9.3-S1 -> 9.11.29-S1 and     9.16.8-S1 -> 9.16.13-S1 of BIND 9 Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.11     of the BIND 9.17 development branch, when a vulnerable version of named receives a malformed IXFR     triggering the flaw described above, the named process will terminate due to a failed assertion the next     time the transferred secondary zone is refreshed. (CVE-2021-25214)

  - An issue was discovered in GNOME GLib before 2.66.6 and 2.67.x before 2.67.3. The function g_bytes_new has     an integer overflow on 64-bit platforms due to an implicit cast from 64 bits to 32 bits. The overflow     could potentially lead to memory corruption. (CVE-2021-27219)
