Mandriva Linux Security Advisory : php (MDVSA-2011:197)

This script is Copyright (C) 2012-2015 Tenable Network Security, Inc.


Synopsis :

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

Description :

Multiple vulnerabilities has been discovered and corrected in php :

Integer overflow in the exif_process_IFD_TAG function in exif.c in the
exif extension in PHP 5.4.0beta2 on 32-bit platforms allows remote
attackers to read the contents of arbitrary memory locations or cause
a denial of service via a crafted offset_val value in an EXIF header
in a JPEG file, a different vulnerability than CVE-2011-0708
(CVE-2011-4566).

PHP before 5.3.9 computes hash values for form parameters without
restricting the ability to trigger hash collisions predictably, which
allows remote attackers to cause a denial of service (CPU consumption)
by sending many crafted parameters (CVE-2011-4885).

The updated packages have been patched to correct this issue.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 6.4
(CVSS2#AV:N/AC:L/Au:N/C:P/I:N/A:P)
CVSS Temporal Score : 5.0
(CVSS2#E:POC/RL:OF/RC:C)
Public Exploit Available : true
