Summary


Inadequate enforcement of fixed-length buffer limits allows an
attacker to overflow a buffer on the stack, potentially enabling
the execution of arbitrary code when a maliciously-crafted
image is opened.

CVS-2008-5317

An integer sign error in reading image gamma data could allow an
attacker to cause an under-sized buffer to be allocated for
subsequent image data, with unknown consequences potentially
including the execution of arbitrary code if a maliciously-crafted
image is opened.

For the stable distribution (etch), these problems have been fixed in
version 1.14-1.1+etch1.

For the upcoming stable distribution (lenny), and the unstable
distribution (sid), these problems are fixed in version 1.17.dfsg-1.

We recommend that you upgrade your lcms packages.
