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

  - A vulnerability was found in libarchive. A specially     crafted MTREE file could cause a small out-of-bounds     read, potentially disclosing a small amount of     application memory.(CVE-2015-8925)

  - A vulnerability was found in libarchive. An attempt to     create an ISO9660 volume with 2GB or 4GB filenames     could cause the application to crash.(CVE-2016-6250)

  - A vulnerability was found in libarchive. A specially     crafted RAR file could cause the application to read     memory beyond the end of the decompression     buffer.(CVE-2015-8934)

  - A vulnerability was found in libarchive's handling of     7zip data. A specially crafted 7zip file can cause a     integer overflow resulting in memory corruption that     can lead to code execution.(CVE-2016-4300)

  - A vulnerability was found in libarchive. A specially     crafted 7Z file could trigger a NULL pointer     dereference, causing the application to     crash.(CVE-2015-8922)

  - Undefined behavior (signed integer overflow) was     discovered in libarchive, in the ISO parser. A crafted     file could potentially cause denial of     service.(CVE-2016-5844)

  - A vulnerability was found in libarchive. A specially     crafted AR archive could cause the application to read     a single byte of application memory, potentially     disclosing it to the attacker.(CVE-2015-8920)

  - A vulnerability was found in libarchive. A specially     crafted mtree file could cause libarchive to read     beyond a statically declared structure, potentially     disclosing application memory.(CVE-2015-8921)

  - A vulnerability was found in libarchive. A specially     crafted LZA/LZH file could cause a small out-of-bounds     read, potentially disclosing a few bytes of application     memory.(CVE-2015-8919)

  - A vulnerability was found in libarchive. A specially     crafted ISO file could cause the application to consume     resources until it hit a memory limit, leading to a     crash or denial of service.(CVE-2015-8930)

  - A vulnerability was found in libarchive. A specially     crafted TAR file could trigger an out-of-bounds read,     potentially causing the application to disclose a small     amount of application memory.(CVE-2015-8924)

  - A vulnerability was found in libarchive. A specially     crafted MTREE file could cause a limited out-of-bounds     read, potentially disclosing contents of application     memory.(CVE-2015-8928)

  - A vulnerability was found in libarchive. A specially     crafted CAB file could cause the application     dereference a NULL pointer, leading to a     crash.(CVE-2015-8917)

  - A vulnerability was found in libarchive. A specially     crafted RAR file could cause the application     dereference a NULL pointer, leading to a     crash.(CVE-2015-8916)

  - A vulnerability was found in libarchive's handling of     RAR archives. A specially crafted RAR file can cause a     heap overflow, potentially leading to code execution in     the context of the application.(CVE-2016-4302)

  - Undefined behavior (invalid left shift) was discovered     in libarchive, in how Compress streams are identified.
    This could cause certain files to be mistakenly     identified as Compress archives and fail to     read.(CVE-2015-8932)

  - A vulnerability was found in libarchive. A specially     crafted gzip file can cause libarchive to allocate     memory without limit, eventually leading to a     crash.(CVE-2016-7166)

  - Undefined behavior (signed integer overflow) was     discovered in libarchive, in the MTREE parser's     calculation of maximum and minimum dates. A crafted     mtree file could potentially cause denial of     service.(CVE-2015-8931)

  - A flaw was found in the way libarchive handled hardlink     archive entries of non-zero size. Combined with flaws     in libarchive's file system sandboxing, this issue     could cause an application using libarchive to     overwrite arbitrary files with arbitrary data from the     archive.(CVE-2016-5418)

  - Integer signedness error in the archive_write_zip_data     function in archive_write_set_format_zip.c in     libarchive 3.1.2 and earlier, when running on 64-bit     machines, allows context-dependent attackers to cause a     denial of service (crash) via unspecified vectors,     which triggers an improper conversion between unsigned     and signed types, leading to a buffer     overflow.(CVE-2013-0211)

  - A vulnerability was found in libarchive. A specially     crafted zip file can provide an incorrect compressed     size, which may allow an attacker to place arbitrary     code on the heap and execute it in the context of the     application.(CVE-2016-1541)

  - A vulnerability was found in libarchive. A specially     crafted cpio archive containing a symbolic link to a     ridiculously large target path can cause memory     allocation to fail, resulting in any attempt to view or     extract the archive crashing.(CVE-2016-4809)

  - A vulnerability was found in libarchive. A specially     crafted ZIP file could cause a few bytes of application     memory in a 256-byte region to be     disclosed.(CVE-2015-8923)

  - A vulnerability was found in libarchive. A specially     crafted RAR file could cause the application to     disclose a 128k block of memory from an uncontrolled     location.(CVE-2015-8926)

The remote MiracleLinux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the AXSA:2016-661:01 advisory.

    Libarchive is a programming library that can create and read several different     streaming archive formats, including most popular tar variants, several cpio     formats, and both BSD and GNU ar variants. It can also write shar archives and     read ISO9660 CDROM images and ZIP archives.
