## Description

archive\_read\_support\_format\_tar.c in libarchive before 2.2.4 allows
user-assisted remote attackers to cause a denial of service (crash) via (1)
an end-of-file condition within a tar header that follows a pax extension
header or (2) a malformed pax extension header in an (a) PAX or a (b) TAR
archive, which results in a NULL pointer dereference, a different issue
than CVE-2007-3644.
