Mandriva Linux Security Advisory : libarchive (MDVSA-2013:147)

This script is Copyright (C) 2013-2014 Tenable Network Security, Inc.


Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

A vulnerability has been found and corrected in libarchive :

Fabian Yamaguchi reported a read buffer overflow flaw in libarchive on
64-bit systems where sizeof(size_t) is equal to 8. In the
archive_write_zip_data() function in libarchive/
archive_write_set_format_zip.c, the 's' parameter is of type size_t
(64 bit, unsigned) and is cast to a 64 bit signed integer. If 's' is
larger than MAX_INT, it will not be set to 'zip->remaining_data_bytes'
even though it is larger than 'zip->remaining_data_bytes', which leads
to a buffer overflow when calling deflate(). This can lead to a
segfault in an application that uses libarchive to create ZIP archives
(CVE-2013-0211).

The updated packages have been patched to correct this issue.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 5.0
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVSS Temporal Score : 4.3
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
