Package        : xpcd
Vulnerability  : buffer overflow
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2005-0074

Erik Sjölund discovered a buffer overflow in pcdsvgaview, an SVGA
PhotoCD viewer.  xpcd-svga is part of xpcd and uses svgalib to display
graphics on the Linux console for which root permissions are required.
A malicious user could overflow a fixed-size buffer and may cause the
program to execute arbitrary code with elevated privileges.

For the stable distribution (woody) this problem has been fixed in
version 2.08-8woody3.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your xpcd-svga package immediately.
