FreeType 2.8.1 has a signed integer overflow in cf2_doFlex in cff/cf2intrp.c.

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

  - FreeType 2.8.1 has a signed integer overflow in cf2_doFlex in cff/cf2intrp.c. (CVE-2025-23022)

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

The remote SUSE Linux SLES12 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2025:1528-1 advisory.

    - CVE-2025-23022: signed integer overflow in cf2_doFlex in cff/cf2intrp.c. (bsc#1235670)

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

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

The version of freetype installed on the remote host is prior to 2.8-14. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-2806 advisory.

    FreeType 2.8.1 has a signed integer overflow in cf2_doFlex in cff/cf2intrp.c. (CVE-2025-23022)

    An out of bounds write exists in FreeType versions 2.13.0 and below when attempting to parse font subglyph     structures related to TrueType GX and variable font files. The vulnerable code assigns a signed short     value to an unsigned long and then adds a static value causing it to wrap around and allocate too small of     a heap buffer. The code then writes up to 6 signed long integers out of bounds relative to this buffer.
    This may result in arbitrary code execution. This vulnerability may have been exploited in the wild.
    (CVE-2025-27363)

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

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