xine-lib: VCD MRL buffer overflow Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200408-18 (xine-lib: VCD MRL buffer overflow) xine-lib contains a bug where it is possible to overflow the vcd:// input source identifier management buffer through carefully crafted playlists. Impact A possible hacker may construct a carefully-crafted playlist file which will cause xine-lib to execute arbitrary code with the permissions of the user. In order to conform with the generic naming standards of most Unix-like systems, playlists can have extensions other than .asx (the standard xine playlist format), and made to look like another file (MP3, AVI, or MPEG for example). If a possible hacker crafts a playlist with a valid header, they can insert a VCD playlist line that can cause a buffer overflow and possible shellcode execution. Workaround There is no known workaround at this time. All users are encouraged to upgrade to the latest available version of xine-lib. References: http://www.open-security.org/advisories/6 Solution: All xine-lib users should upgrade to the latest version: # emerge sync # emerge -pv ">=media-libs/xine-lib-1_rc5-r3" # emerge ">=media-libs/xine-lib-1_rc5-r3" Network Security Threat Level: Medium Networks Security ID: Vulnerability Assessment Copyright: (C) 2005 Michel Arboi |
