47b4e713-6513-11e3-868f-0025905a4771PHP5 -- memory corruption in openssl_x509_parse()

Stefan Esser reports:

The PHP function openssl_x509_parse() uses a helper function called asn1_time_to_time_t() to convert timestamps from ASN1 string format into integer timestamp values. The parser within this helper function is not binary safe and can therefore be tricked to write up to five NUL bytes outside of an allocated buffer.

This problem can be triggered by x509 certificates that contain NUL bytes in their notBefore and notAfter timestamp fields and leads to a memory corruption that might result in arbitrary code execution.

Depending on how openssl_x509_parse() is used within a PHP application the attack requires either a malicious cert signed by a compromised/malicious CA or can be carried out with a self-signed cert.

31b145f2-d9d3-49a9-8023-11cf742205dcPHP5 -- Heap corruption in XML parser

The PHP development team reports:

ext/xml/xml.c in PHP before 5.3.27 does not properly consider parsing depth, which allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a crafted document that is processed by the xml_parse_into_struct function.
