The remote Redhat Enterprise Linux 5 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: stack overflow in read_fragment_table_4 due to fix for CVE-2015-4645 (CVE-2015-4646)

  - Integer overflow in the read_fragment_table_4 function in unsquash-4.c in Squashfs and sasquatch allows     remote attackers to cause a denial of service (application crash) via a crafted input, which triggers a     stack-based buffer overflow. (CVE-2015-4645)

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

The remote host is affected by the vulnerability described in GLSA-201701-73 (SQUASHFS: Multiple vulnerabilities)

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

    Remote attackers, by enticing a user to process a specially crafted       SQUASHFS image, could execute arbitrary code with the privileges of the       process.
  Workaround :

    There is no known workaround at this time.

Security fix for CVE-2015-4645 / CVE-2015-4646

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4591-1 advisory.

  - Integer overflow in the read_fragment_table_4 function in unsquash-4.c in Squashfs and sasquatch allows     remote attackers to cause a denial of service (application crash) via a crafted input, which triggers a     stack-based buffer overflow. (CVE-2015-4645)

  - (1) unsquash-1.c, (2) unsquash-2.c, (3) unsquash-3.c, and (4) unsquash-4.c in Squashfs and sasquatch allow     remote attackers to cause a denial of service (application crash) via a crafted input. (CVE-2015-4646)

  - squashfs_opendir in unsquash-1.c in Squashfs-Tools 4.5 stores the filename in the directory entry; this is     then used by unsquashfs to create the new file during the unsquash. The filename is not validated for     traversal outside of the destination directory, and thus allows writing to locations outside of the     destination. (CVE-2021-40153)

  - squashfs_opendir in unsquash-2.c in Squashfs-Tools 4.5 allows Directory Traversal, a different     vulnerability than CVE-2021-40153. A squashfs filesystem that has been crafted to include a symbolic link     and then contents under the same filename in a filesystem can cause unsquashfs to first create the     symbolic link pointing outside the expected directory, and then the subsequent write operation will cause     the unsquashfs process to write through the symbolic link elsewhere in the filesystem. (CVE-2021-41072)

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

New squashfs-tools packages are available for Slackware 14.2 and
-current to fix security issues.

The remote Redhat Enterprise Linux 7 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: possible Directory Traversal via symbolic link (CVE-2021-41072)

  - Integer overflow in the read_fragment_table_4 function in unsquash-4.c in Squashfs and sasquatch allows     remote attackers to cause a denial of service (application crash) via a crafted input, which triggers a     stack-based buffer overflow. (CVE-2015-4645)

  - (1) unsquash-1.c, (2) unsquash-2.c, (3) unsquash-3.c, and (4) unsquash-4.c in Squashfs and sasquatch allow     remote attackers to cause a denial of service (application crash) via a crafted input. (CVE-2015-4646)

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

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.

  - (1) unsquash-1.c, (2) unsquash-2.c, (3) unsquash-3.c,     and (4) unsquash-4.c in Squashfs and sasquatch allow     remote attackers to cause a denial of service     (application crash) via a crafted input.(CVE-2015-4646)
