Chris Evans discovered several stack overflows in the versions of
libXpm shipped by X.Org, XFree86, and LessTif. These overflows
were fixed in the Warty development tree before its release.
Mathieu Herrb of OpenBSD subsequently discovered that the original
patch was insufficient to address these overflows, and thus the
version of libxpm4 shipped with Warty is still vulnerable to the
original overflows.
These overflows do not allow privilege escalation through the X
server; the overflows are in a client-side library, allowing
arbitrary code execution with the privileges of the user
viewing a malicious pixmap.
