Mandriva Linux Security Advisory : libtiff (MDVSA-2012:174)

This script is Copyright (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

Multiple vulnerabilities was found and corrected in libtiff :

Heap-based buffer overflow in tif_pixarlog.c in LibTIFF before 4.0.3
allows remote attackers to cause a denial of service (application
crash) and possibly execute arbitrary code via a crafted TIFF image
using the PixarLog Compression format (CVE-2012-4447).

ppm2tiff does not check the return value of the TIFFScanlineSize
function, which allows remote attackers to cause a denial of service
(crash) and possibly execute arbitrary code via a crafted PPM image
that triggers an integer overflow, a zero-memory allocation, and a
heap-based buffer overflow (CVE-2012-4564).

The updated packages have been patched to correct these issues.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.9
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
