The JPEG library is vulnerable to a Denial of Service.
|Package||media-libs/jpeg on all architectures|
|Affected versions||< 6b-r7|
|Unaffected versions||>= 6b-r7|
The JPEG library is able to load, handle and manipulate images in the JPEG format.
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"
