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 Rocky Linux 9.2 host has a package installed that is affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_0494 advisory.

    This advisory aggregates security fixes for the squashfs-tools SRPM in CIQ LTS 9.2. It addresses 3 CVEs:
    CVE-2021-41072, CVE-2012-4024, CVE-2012-4025.

Tenable has extracted the preceding description block directly from the CIQ security advisory.

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

The Rocky Linux 8.6 host has a package installed that is affected by multiple vulnerabilities as referenced in the CIQ ciqsa-2026_0261 advisory.

    This advisory aggregates security fixes for the squashfs-tools SRPM in CIQ LTS 8.6. It addresses 3 CVEs:
    CVE-2021-41072, CVE-2012-4024, CVE-2012-4025.

Tenable has extracted the preceding description block directly from the CIQ security advisory.

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

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). 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

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)
