Memory leak in the __archive_read_get_extract function in archive_read_extract2.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service via a tar file.

Technical Analysis

CVE-2015-8929 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.

A successful exploit results in availability disruption (denial of service), with a CVSS base score of 5.5.

From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
