Debian DSA-2026-1: Critical Netpbm Buffer Overflow Denial Of Service

Marc Schoenefeld discovered a stack-based buffer overflow in the XPM reader
implementation in netpbm-free, a suite of image manipulation utilities.
An attacker could cause a denial of service (application crash) or possibly
execute arbitrary code via an XPM image file that contains a crafted header
field associated with a large color index value.


For the stable distribution (lenny), this problem has been fixed in
version 2:10.0-12+lenny1.

For the testing distribution (squeeze), this problem has been fixed in
version 2:10.0-12.1+squeeze1.

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


Due to a problem with the archive system it is not possible to release
all architectures. The missing architectures will be installed into the
archive once they become available.

We recommend that you upgrade your netpbm-free package.
