Integer overflow in the queue_init function in unsquashfs.c in unsquashfs in Squashfs 4.2 and earlier allows remote attackers to execute arbitrary code via a crafted block_log field in the superblock of a .sqsh file, leading to a heap-based buffer overflow.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - squashfs-tools: integer overflow in queue_init() may lead to abitrary code execution (CVE-2012-4025)

  - squashfs-tools: stack overflow in read_fragment_table_4 due to fix for CVE-2015-4645 (CVE-2015-4646)

  - Stack-based buffer overflow in the get_component function in unsquashfs.c in unsquashfs in Squashfs 4.2     and earlier allows remote attackers to execute arbitrary code via a crafted list file (aka a crafted file     for the -ef option). NOTE: probably in most cases, the list file is a trusted file constructed by the     program's user; however, there are some realistic situations in which a list file would be obtained from     an untrusted remote source. (CVE-2012-4024)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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

  - Integer overflow in the queue_init function in     unsquashfs.c in unsquashfs in Squashfs 4.2 and earlier     allows remote attackers to execute arbitrary code via a     crafted block_log field in the superblock of a .sqsh     file, leading to a heap-based buffer     overflow.(CVE-2012-4025)

  - Stack-based buffer overflow in the get_component     function in unsquashfs.c in unsquashfs in Squashfs 4.2     and earlier allows remote attackers to execute     arbitrary code via a crafted list file (aka a crafted     file for the -ef option).

The remote host is affected by the vulnerability described in GLSA-201612-40 (SQUASHFS: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in SQUASHFS. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to open a specially crafted .sqsh       file using unsquashfs; possibly resulting in the execution of arbitrary       code with the privileges of the process, or a Denial of Service       condition.
  Workaround :

    There is no known workaround at this time.

Updated squashfs-tools packages fix security vulnerabilities :

remote arbitrary code execution via crafted list file (CVE-2012-4024).

integer overflow in queue_init() may lead to arbitrary code execution (CVE-2012-4025).

Backported fixes for bz 842458 (CVE-2012-4024) and bz 842460 (CVE-2012-4025) Backported fix for bz 842458 (CVE-2012-4024)
