18 Mar 2019
Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 924678.
In Mitre's CVE dictionary: CVE-2018-14498.
More information:

It was discovered that there was a denial of service vulnerability in the libjpeg-turbo CPU-optimised JPEG image library. A heap-based buffer over-read could be triggered by a specially-crafted bitmap (BMP) file.

  • CVE-2018-14498

    get_8bit_row in rdbmp.c in libjpeg-turbo through 1.5.90 and MozJPEG through 3.3.1 allows attackers to cause a denial of service (heap-based buffer over-read and application crash) via a crafted 8-bit BMP in which one or more of the color indices is out of range for the number of palette entries.

For Debian 8 Jessie, these problems have been fixed in version 1:1.3.1-12+deb8u2.

We recommend that you upgrade your libjpeg-turbo packages.
