Ubuntu 4.10 : libxpm4 vulnerability (USN-27-1)
High Nessus Plugin ID 20642
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionChris 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.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
