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.
