The PHP development team reports:

Integer overflow in the SdnToJewish function in jewish.c in the Calendar component in PHP before 5.3.26 and 5.4.x before 5.4.16 allows context-dependent attackers to cause a denial of service (application hang) via a large argument to the jdtojewish function.

>= 5.4.0 lt 5.4.16

< 5.3.26

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.

>= 5.4.0 lt 5.4.23

< 5.3.28

>= 5.5.0 lt 5.5.7

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.

< 5.3.27

The PHP development team reports:

A Heap-based buffer overflow flaw was found in the php quoted_printable_encode() function. A remote attacker could use this flaw to cause php to crash or execute arbirary code with the permission of the user running php

< 5.4.16

< 5.3.26
