The VideoLAN VLC program displays multimedia documents. It has two
vulnerabilities.
The libty_plugin can be used to open TiVo files. It has two
vulnerabilities.
If the TV file contains long data, a buffer overflow occurs in
parse_master(). [grav:2/4; CVE-2008-4654, TKADV2008-010,
VideoLAN-SA-0809]
A malformed file can create several integer overflows. [grav:2/4;
BID-31867, CVE-2008-4686]
An attacker can therefore create a malformed TiVo file in order to
create a denial of service or to execute code on computers of VLC
users.
