XFree86 Multiple Unspecified Integer Overflow Vulnerabilities
Multiple integer-overflow vulnerabilities have been discovered in the XFree86 font libraries. The problem occurs because of insufficient sanity checks on integers passed to clients from an X font server. As a result, an unexpected buffer overrun may occur within the stack or heap space of process memory. An attacker could potentially exploit this to execute arbitrary code within a target X client. Precise technical details regarding these vulnerabilities are currently unavailable; as further information is released, this BID will be updated accordingly. |
