sol16015326: libtar vulnerability CVE-2013-4397

Security Advisory

Original Publication Date: 02/04/2016

Vulnerability Description

Multiple integer overflows in the th_read function in lib/block.c in libtar 
before 1.2.20 allow remote attackers to cause a denial of service (crash) and
possibly execute arbitrary code via a long (1) name or (2) link in an archive,
which triggers a heap-based buffer overflow. (CVE-2013-4397)

Impact

A remote attacker may be able to cause a denial-of-service (DoS) or execute 
arbitrary code on the BIG-IP system.
