Mandriva Linux Security Advisory : php (MDVSA-2008:126)

This script is Copyright (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

A number of vulnerabilities have been found and corrected in PHP :

PHP 5.2.1 would allow context-dependent attackers to read portions of
heap memory by executing certain scripts with a serialized data input
string beginning with 'S:', which did not properly track the number of
input bytes being processed (CVE-2007-1649).

A vulnerability in the chunk_split() function in PHP prior to 5.2.4
has unknown impact and attack vectors, related to an incorrect size
calculation (CVE-2007-4660).

The htmlentities() and htmlspecialchars() functions in PHP prior to
5.2.5 accepted partial multibyte sequences, which has unknown impact
and attack vectors (CVE-2007-5898).

The output_add_rewrite_var() function in PHP prior to 5.2.5 rewrites
local forms in which the ACTION attribute references a non-local URL,
which could allow a remote attacker to obtain potentially sensitive
information by reading the requests for this URL (CVE-2007-5899).

The escapeshellcmd() API function in PHP prior to 5.2.6 has unknown
impact and context-dependent attack vectors related to incomplete
multibyte characters (CVE-2008-2051).

Weaknesses in the GENERATE_SEED macro in PHP prior to 4.4.8 and 5.2.5
were discovered that could produce a zero seed in rare circumstances
on 32bit systems and generations a portion of zero bits during
conversion due to insufficient precision on 64bit systems
(CVE-2008-2107, CVE-2008-2108).

The IMAP module in PHP uses obsolete API calls that allow
context-dependent attackers to cause a denial of service (crash) via a
long IMAP request (CVE-2008-2829).

The updated packages have been patched to correct these issues.

Solution :

Update the affected packages.

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 8.7
(CVSS2#E:ND/RL:OF/RC:C)
