Debian DSA-1455-1 : libarchive - denial of service
High Nessus Plugin ID 29902
The remote Debian host is missing a security-related update.
Several local/remote vulnerabilities have been discovered in libarchive1, a single library to read/write tar, cpio, pax, zip, iso9660 archives. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2007-3641 It was discovered that libarchive1 would miscompute the length of a buffer resulting in a buffer overflow if yet another type of corruption occurred in a pax extension header. - CVE-2007-3644 It was discovered that if an archive prematurely ended within a pax extension header the libarchive1 library could enter an infinite loop. - CVE-2007-3645 If an archive prematurely ended within a tar header, immediately following a pax extension header, libarchive1 could dereference a NULL pointer.
Upgrade the libarchive package. The old stable distribution (sarge), does not contain this package. For the stable distribution (etch), these problems have been fixed in version 1.2.53-2etch1.
