An attacker who submits a crafted tar file with size in header struct being 0 may be able to trigger an calling of malloc(0) for a variable gnu_longlink, causing an out-of-bounds read. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Multiple directory traversal vulnerabilities in the (1) tar_extract_glob and (2) tar_extract_all functions in libtar 1.2.20 and earlier allow remote attackers to overwrite arbitrary files via a .. Rated medium severity (CVSS 5.8), this vulnerability is remotely exploitable. No vendor patch available.
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. Rated medium severity (CVSS 6.8), this vulnerability is remotely exploitable. Public exploit code available and no vendor patch available.
