Detail

Several remote vulnerabilities have been discovered in PHP 5, an hypertext preprocessor. The Common Vulnerabilities and Exposures project identifies the following problems:

CVE-2010-1917

The fnmatch function can be abused to conduct denial of service attacks (by crashing the interpreter) by the means of a stack overflow.

CVE-2010-2225

The SplObjectStorage unserializer allows attackers to execute arbitrary code via serialized data by the means of a use-after-free vulnerability.

MOPS-60

The default sessions serializer does not correctly handle a special marker, which allows an attacker to inject arbitrary variables into the session and possibly exploit vulnerabilities in the unserializer.

For the vulnerability described by CVE-2010-1128 (predictable entropy for the Linear Congruential Generator used to generate session ids,) we do not consider upstream's solution to be sufficient. It is recommended to uncomment the 'session.entropy_file' and 'session.entropy_length' settings in the php.ini files. Further improvements can be achieved by setting 'session.hash_function' to 1 (one) and incrementing the value of 'session.entropy_length.'

For the stable distribution (lenny), these problems have been fixed in version 5.2.6.dfsg.1-1+lenny9.

For the testing distribution (squeeze) and the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your php5 packages.

Title: USN-989-1 -- php5 vulnerabilities
Description: Auke van Slooten discovered that PHP incorrectly handled certain xmlrpc requests. An attacker could exploit this issue to cause the PHP server to crash, resulting in a denial of service. This issue only affected Ubuntu 6.06 LTS, 8.04 LTS, 9.04 and 9.10. It was discovered that the pseudorandom number generator in PHP did not provide the expected entropy. An attacker could exploit this issue to predict values that were intended to be random, such as session cookies. This issue only affected Ubuntu 6.06 LTS, 8.04 LTS, 9.04 and 9.10. It was discovered that PHP did not properly handle directory pathnames that lacked a trailing slash character. An attacker could exploit this issue to bypass safe_mode restrictions. This issue only affected Ubuntu 6.06 LTS, 8.04 LTS, 9.04 and 9.10. Grzegorz Stachowiak discovered that the PHP session extension did not properly handle semicolon characters. An attacker could exploit this issue to bypass safe_mode restrictions. This issue only affected Ubuntu 8.04 LTS, 9.04 and 9.10. Stefan Esser discovered that PHP incorrectly decoded remote HTTP chunked encoding streams. An attacker could exploit this issue to cause the PHP server to crash and possibly execute arbitrary code with application privileges. This issue only affected Ubuntu 10.04 LTS. Mateusz Kocielski discovered that certain PHP SQLite functions incorrectly handled empty SQL queries. An attacker could exploit this issue to possibly execute arbitrary code with application privileges. Mateusz Kocielski discovered that PHP incorrectly handled certain arguments to the fnmatch function. An attacker could exploit this flaw and cause the PHP server to consume all available stack memory, resulting in a denial of service. Stefan Esser discovered that PHP incorrectly handled certain strings in the phar extension. An attacker could exploit this flaw to possibly view sensitive information. This issue only affected Ubuntu 10.04 LTS. Stefan Esser discovered that PHP incorrectly handled deserialization of SPLObjectStorage objects. A remote attacker could exploit this issue to view sensitive information and possibly execute arbitrary code with application privileges. This issue only affected Ubuntu 8.04 LTS, 9.04, 9.10 and 10.04 LTS. It was discovered that PHP incorrectly filtered error messages when limits for memory, execution time, or recursion were exceeded. A remote attacker could exploit this issue to possibly view sensitive information. Stefan Esser discovered that the PHP session serializer incorrectly handled the PS_UNDEF_MARKER marker. An attacker could exploit this issue to alter arbitrary session variables
