FreeBSD : png -- Out-of-bounds read (f323f148-d181-11f0-841f-843a4b343614)

high Nessus Plugin ID 277599

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the f323f148-d181-11f0-841f-843a4b343614 advisory.

 https://github.com/pnggroup/libpng/security/advisories/GHSA-9mpm-9pxh-mg4f reports:
 Prior to 1.6.52, an out-of-bounds read vulnerability in libpng's simplified API allows reading up to 1012 bytes beyond the png_sRGB_base[512] array when processing valid palette PNG images with partial transparency and gamma correction. The PNG files that trigger this vulnerability are valid per the PNG specification; the bug is in libpng's internal state management.

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

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

Solution

Update the affected packages.
