high Nessus Plugin ID 153137

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 21.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5068-1 advisory.

 - ** DISPUTED ** In the GD Graphics Library (aka LibGD) through 2.2.5, there is a heap-based buffer over- read in tiffWriter in gd_tiff.c. NOTE: the vendor says In my opinion this issue should not have a CVE, since the GD and GD2 formats are documented to be 'obsolete, and should only be used for development and testing purposes.' (CVE-2017-6363)

 - read_header_tga in gd_tga.c in the GD Graphics Library (aka LibGD) through 2.3.2 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted TGA file. (CVE-2021-38115)

 - ** DISPUTED ** gdImageGd2Ptr in gd_gd2.c in the GD Graphics Library (aka LibGD) through 2.3.2 has a double free. NOTE: the vendor's position is The GD2 image format is a proprietary image format of libgd. It has to be regarded as being obsolete, and should only be used for development and testing purposes.
 (CVE-2021-40145)

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 libgd-dev, libgd-tools and / or libgd3 packages.
