Category:Red Hat Local Security Checks
Title:RedHat Update for php53 and php RHSA-2011:1423-01
Summary:The remote host is missing an update for the 'php53 and php'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'php53 and php'
package(s) announced via the referenced advisory.

Vulnerability Insight:
PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Server.

A signedness issue was found in the way the PHP crypt() function handled
8-bit characters in passwords when using Blowfish hashing. Up to three
characters immediately preceding a non-ASCII character (one with the high
bit set) had no effect on the hash result, thus shortening the effective
password length. This made brute-force guessing more efficient as several
different passwords were hashed to the same value. (CVE-2011-2483)

Note: Due to the CVE-2011-2483 fix, after installing this update some users
may not be able to log in to PHP applications that hash passwords with
Blowfish using the PHP crypt() function. Refer to the upstream
'CRYPT_BLOWFISH security fix details' document, linked to in the
References, for details.

An insufficient input validation flaw, leading to a buffer over-read, was
found in the PHP exif extension. A specially-crafted image file could cause
the PHP interpreter to crash when a PHP script tries to extract
Exchangeable image file format (Exif) metadata from the image file.
(CVE-2011-0708)

An integer overflow flaw was found in the PHP calendar extension. A remote
attacker able to make a PHP script call SdnToJulian() with a large value
could cause the PHP interpreter to crash. (CVE-2011-1466)

Multiple memory leak flaws were found in the PHP OpenSSL extension. A
remote attacker able to make a PHP script use openssl_encrypt() or
openssl_decrypt() repeatedly could cause the PHP interpreter to use an
excessive amount of memory. (CVE-2011-1468)

A use-after-free flaw was found in the PHP substr_replace() function. If a
PHP script used the same variable as multiple function arguments, a remote
attacker could possibly use this to crash the PHP interpreter or, possibly,
execute arbitrary code. (CVE-2011-1148)

A bug in the PHP Streams component caused the PHP interpreter to crash if
an FTP wrapper connection was made through an HTTP proxy. A remote attacker
could possibly trigger this issue if a PHP script accepted an untrusted URL
to connect to. (CVE-2011-1469)

An integer signedness issue was found in the PHP zip extension. An attacker
could use a specially-crafted ZIP archive to cause the PHP interpreter to
use an excessive amount of CPU time until the script execution time limit
is reached. (CVE-2011-1471)

A stack-based buffer overflow flaw was found in the way the PHP socket
extension handled long AF_UNIX socket addresses. An attacker able to mak ...
