ID: | 200606-11 |
Synopsis
The JPEG library is vulnerable to a Denial of Service.Background
The JPEG library is able to load, handle and manipulate images in the JPEG format.
Affected packages
Package | Vulnerable | Unaffected | Architecture(s) |
---|---|---|---|
media-libs/jpeg | < 6b-r7 | >= 6b-r7 | All supported architectures |
Description
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.
Impact
By enticing a user to load a specially crafted JPEG image file an attacker could cause a Denial of Service, due to memory exhaustion.
Workaround
There is no known workaround at this time.
Resolution
JPEG users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/jpeg-6b-r7"
