X.Org, XFree86: libXpm vulnerabilities libXpm contains several vulnerabilities that could lead to a Denial of Service and arbitrary code execution. X.Org, XFree86 2004-11-19 2004-11-19 68544 remote 6.8.0-r3 6.7.0-r3 6.8.0-r3 4.3.0-r8 4.3.0-r8

libXpm is a pixmap manipulation library for the X Window System, included in both X.Org and XFree86.

Several issues were discovered in libXpm, including integer overflows, out-of-bounds memory accesses, insecure path traversal and an endless loop.

An attacker could craft a malicious pixmap file and entice a user to use it with an application linked against libXpm. This could lead to Denial of Service or arbitrary code execution.

There is no known workaround at this time.
