Trail of Bits used the automated vulnerability discovery tools developed for the DARPA Cyber Grand Challenge to audit zlib. As rsync, a fast, versatile, remote (and local) file-copying tool, uses an embedded copy of zlib, those issues are also present in rsync.

CVE-2016-9840 In order to avoid undefined behavior, remove offset pointer optimization, as this is not compliant with the C standard.

CVE-2016-9841 Only use post-increment to be compliant with the C standard.

CVE-2016-9842 In order to avoid undefined behavior, do not shift negative values, as this is not compliant with the C standard.

CVE-2016-9843 In order to avoid undefined behavior, do not pre-decrement a pointer in big-endian CRC calculation, as this is not compliant with the C standard.

CVE-2018-5764 Prevent remote attackers from being able to bypass the argument-sanitization protection mechanism by ignoring --protect-args when already sent by client.

For Debian 8 'Jessie', these problems have been fixed in version 3.1.1-3+deb8u2.

We recommend that you upgrade your rsync packages.

The remote Ubuntu 16.04 LTS / 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4292-1 advisory.

    It was discovered that rsync incorrectly handled pointer arithmetic in zlib. An attacker could use this     issue to cause rsync to crash, resulting in a denial of service, or possibly execute arbitrary code.

    Supported versions that are affected are 5.5.61 and prior, 5.6.41 and prior, 5.7.23 and prior and 8.0.12     and prior. Easily exploitable vulnerability allows high privileged attacker with network access via     multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in     unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server.
    (CVE-2018-3282)

  - Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Connection Handling).
    Supported versions that are affected are 5.6.42 and prior, 5.7.24 and prior and 8.0.13 and prior.
    Difficult to exploit vulnerability allows low privileged attacker with access to the physical     communication segment attached to the hardware where the MySQL Server executes to compromise MySQL Server.
    Successful attacks of this vulnerability can result in unauthorized access to critical data or complete     access to all MySQL Server accessible data and unauthorized ability to cause a hang or frequently     repeatable crash (complete DOS) of MySQL Server. (CVE-2019-2503)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the mariadb-connector-c package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - inftrees.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging     improper pointer arithmetic. (CVE-2016-9840)

  - inffast.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging     improper pointer arithmetic. (CVE-2016-9841)

  - The inflateMark function in inflate.c in zlib 1.2.8 might allow context-dependent attackers to have     unspecified impact via vectors involving left shifts of negative integers. (CVE-2016-9842)

  - The crc32_big function in crc32.c in zlib 1.2.8 might allow context-dependent attackers to have     unspecified impact via vectors involving big-endian CRC calculation. (CVE-2016-9843)

  - zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many     distant matches. (CVE-2018-25032)

  - zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a     large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some     common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g.,     see the nodejs/node reference). (CVE-2022-37434)

According to the versions of the deltarpm package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - inftrees.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging     improper pointer arithmetic. (CVE-2016-9840)

  - inffast.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging     improper pointer arithmetic. (CVE-2016-9841)
