Summaryinfo

A vulnerability was found in elfutils 0.161 and classified as problematic. The impacted element is the function read_long_names. The manipulation results in path traversal. This vulnerability is identified as CVE-2014-9447. There is not any exploit available.

Detailsinfo

A vulnerability classified as critical has been found in elfutils 0.161. Affected is the function read_long_names. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on integrity, and availability. CVE summarizes:

Directory traversal vulnerability in the read_long_names function in libelf/elf_begin.c in elfutils 0.152 and 0.161 allows remote attackers to write to arbitrary files to the root directory via a / (slash) in a crafted archive, as demonstrated using the ar program.
