xine-ui is a skin-based user interface for xine. xine is a free multimedia player. It plays CDs, DVDs, and VCDs, and can also decode other common multimedia formats.
Ludwig Nussel discovered that xine-ui incorrectly implements formatted printing.
By constructing a malicious playlist file, a remote attacker could exploit these vulnerabilities to execute arbitrary code with the rights of the user running the application.
There is no known workaround at this time.
All xine-ui users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/xine-ui-0.99.4-r5"
