|Gentoo Linux Security Advisory
Title: JPEG library: Denial of Service (GLSA 200606-11)
Date: June 11, 2006
Updated: July 29, 2006
The JPEG library is vulnerable to a Denial of Service.
The JPEG library is able to load, handle and manipulate images in the JPEG format.
Vulnerable: < 6b-r7
Unaffected: >= 6b-r7
Architectures: All supported architectures
Tavis Ormandy of the Gentoo Linux Auditing Team discovered that the vulnerable JPEG library ebuilds compile JPEG without the --maxmem feature which is not recommended.
By enticing a user to load a specially crafted JPEG image file an attacker could cause a Denial of Service, due to memory exhaustion.
There is no known workaround at this time.
JPEG users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/jpeg-6b-r7"
