Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)

xine-ui improperly handles format strings, possibly allowing for the execution of arbitrary code.

2.  Impact Information


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.


Due to the improper handling and use of format strings, the errors_create_window() function in errors.c does not safely write data to memory.


An attacker could entice a user to open a specially crafted media file with xine-ui, and possibly execute arbitrary code.

3.  Resolution Information


There is no known workaround at this time.


All xine-ui users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/xine-ui-0.99.5_pre20060716"
