xine-lib: Multiple vulnerabilities

xine-lib: Multiple vulnerabilities xine-lib contains several vulnerabilities potentially allowing the execution of arbitrary code. xine-lib 2004-09-22 2006-05-22 64348 remote 1_rc6 1_rc5-r3

xine-lib is a multimedia library which can be utilized to create multimedia frontends.

xine-lib contains two stack-based overflows and one heap-based overflow. In the code reading VCD disc labels, the ISO disc label is copied into an unprotected stack buffer of fixed size. Also, there is a buffer overflow in the code that parses subtitles and prepares them for display (XSA-2004-4). Finally, xine-lib contains a heap-based overflow in the DVD sub-picture decoder (XSA-2004-5).

(Please note that the VCD MRL issue mentioned in XSA-2004-4 was fixed with GLSA 200408-18.)

With carefully-crafted VCDs, DVDs, MPEGs or subtitles, an attacker may cause xine-lib to execute arbitrary code with the permissions of the user.

There is no known workaround at this time.

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


    # emerge sync
    
    # emerge -pv ">=media-libs/xine-lib-1_rc6"
    # emerge ">=media-libs/xine-lib-1_rc6"
