Multiple integer overflows in the thread 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.

Multiple directory traversal vulnerabilities in the (1) tarextractglob and (2) tarextractall functions in libtar 1.2.20 and earlier allow remote attackers to overwrite arbitrary files via a .. (dot dot) in a crafted tar file.
