Detailsinfo

A vulnerability, which was classified as critical, was found in GraphicsMagick 1.4 snapshot-20181209 Q8 (Image Processing Software). This affects the function WriteTGAImage of the file tga.c. The manipulation as part of a Image File leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In GraphicsMagick 1.4 snapshot-20181209 Q8, there is a heap-based buffer overflow in the WriteTGAImage function of tga.c, which allows attackers to cause a denial of service via a crafted image file, because the number of rows or columns can exceed the pixel-dimension restrictions of the TGA specification.

The bug was discovered 12/12/2018. The weakness was presented 12/17/2018 (Website). The advisory is shared at hg.graphicsmagick.org. This vulnerability is uniquely identified as CVE-2018-20184 since 12/17/2018. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Technical details are known, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 5 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 119889 (Debian DLA-1619-1 : graphicsmagick security update), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 171803 (SUSE Enterprise Linux Security Update for GraphicsMagick (SUSE-SU-2019:13923-1)).

Upgrading eliminates this vulnerability. A possible mitigation has been published 2 weeks after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (119889) and SecurityFocus (BID 106229†). See VDB-101941, VDB-104966, VDB-112664 and VDB-125831 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
