GLSA-200501-07 : xine-lib: Multiple overflows

Critical Nessus Plugin ID 16398


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200501-07 (xine-lib: Multiple overflows)

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 :

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.
Workaround :

There is no known workaround at this time.


All xine-lib users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose media-libs/xine-lib
