Detailsinfo

A vulnerability, which was classified as problematic, was found in SystemTap 1.0. This affects an unknown part. The manipulation with an unknown input leads to a access control vulnerability. CWE is classifying the issue as CWE-264. This is going to have an impact on availability. The summary by CVE is:

SystemTap 1.0, when the --unprivileged option is used, does not properly restrict certain data sizes, which allows local users to (1) cause a denial of service or gain privileges via a print operation with a large number of arguments that trigger a kernel stack overflow, (2) cause a denial of service via crafted DWARF expressions that trigger a kernel stack frame overflow, or (3) cause a denial of service (infinite loop) via vectors that trigger creation of large unwind tables, related to Common Information Entry (CIE) and Call Frame Instruction (CFI) records.

The weakness was shared 10/22/2009 by Jan Lieskovsky (oss-sec). The advisory is shared at openwall.com. This vulnerability is uniquely identified as CVE-2009-2911. An attack has to be approached locally. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.
