Ubuntu 16.04 ESM / 18.04 ESM / 22.04 ESM : VIPS vulnerabilities (USN-6437-1)

high Nessus Plugin ID 183342


The remote Ubuntu host is missing one or more security updates.


The remote Ubuntu 16.04 ESM / 18.04 ESM / 22.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6437-1 advisory.

- In libvips before 8.6.3, a NULL function pointer dereference vulnerability was found in the vips_region_generate function in region.c, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted image file. This occurs because of a race condition involving a failed delayed load and other worker threads. (CVE-2018-7998)

- libvips before 8.7.4 generates output images from uninitialized memory locations when processing corrupted input image data because iofuncs/memory.c does not zero out allocated memory. This can result in leaking raw process memory contents through the output image. (CVE-2019-6976)

- im_vips2dz in /libvips/libvips/deprecated/im_vips2dz.c in libvips before 8.8.2 has an uninitialized variable which may cause the leakage of remote server path or stack address. (CVE-2020-20739)

- Division-By-Zero vulnerability in Libvips 8.10.5 in the function vips_eye_point, eye.c#L83, and function vips_mask_point, mask.c#L85. (CVE-2021-27847)

- libvips is a demand-driven, horizontally threaded image processing library. A specially crafted SVG input can cause libvips versions 8.14.3 or earlier to segfault when attempting to parse a malformed UTF-8 character. Users should upgrade to libvips version 8.14.4 (or later) when processing untrusted input.

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