+ <p>
+ xine-lib is a multimedia library which can be utilized to create
+ multimedia frontends.

+ Ariel Berkman discovered that xine-lib reads specific input data
+ into an array without checking the input size in demux_aiff.c, making
+ it vulnerable to a buffer overflow (CAN-2004-1300) . iDefense
+ discovered that the PNA_TAG handling code in pnm_get_chunk() does not
+ check if the input size is larger than the buffer size (CAN-2004-1187).
+ iDefense also discovered that in this same function, a negative value
+ could be given to an unsigned variable that specifies the read length
+ of input data (CAN-2004-1188).

+ <impact type="normal">
+ <p>
+ A remote attacker could craft a malicious movie or convince a
+ targeted user to connect to a malicious PNM server, which could result
+ in the execution of arbitrary code with the rights of the user running
+ any xine-lib frontend.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All xine-lib users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose media-libs/xine-lib</code>
