Detailsinfo

A vulnerability classified as problematic was found in OpenJPEG 2.2.0 (Image Processing Software). Affected by this vulnerability is the function opj_aligned_alloc_n in the library lib/openjp2/image.c of the file bin/jp2/convertbmp.c of the component biBitCount. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect availability. The summary by CVE is:

The bmp_read_info_header function in bin/jp2/convertbmp.c in OpenJPEG 2.2.0 does not reject headers with a zero biBitCount, which allows remote attackers to cause a denial of service (memory allocation failure) in the opj_image_create function in lib/openjp2/image.c, related to the opj_aligned_alloc_n function in opj_malloc.c.

The bug was discovered 08/14/2017. The weakness was published 08/21/2017 by Agostino Sarubbo with Gentoo (Website). The advisory is shared at blogs.gentoo.org. This vulnerability is known as CVE-2017-12982 since 08/21/2017. The attack can be launched remotely. The exploitation doesn't need any form of authentication. 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 7 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 102932 (Fedora 26 : mingw-openjpeg2 / openjpeg2 (2017-06cace06ce)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 277692 (Fedora Security Update for openjpeg2 (FEDORA-2017-a5bb95b447)).

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 (102932) and SecurityFocus (BID 100553†). Similar entries are available at VDB-106003, VDB-106004, VDB-106125 and VDB-106126. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
