CVE-2012-2806

Published: 13 August 2012

Heap-based buffer overflow in the get_sos function in jdmarker.c in libjpeg-turbo 1.2.0 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a large component count in the header of a JPEG image.

Notes

this vulnerability was introduced by
http://libjpeg-turbo.svn.sourceforge.net/viewvc/libjpeg-turbo?view=revision&revision=740
which is not in oneiric, precise, and quantal's versions. Also,
example reproducers from the firefox bug report did not crash the
djpeg tool from libjpeg-turbo-tools in those releases.
