CVE-2013-4397 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 5.49% chance of exploitation in the next 30 days.
