PHP : Security Vulnerabilities, CVEs, Published In 2005 (Denial of service)

Multiple integer handling errors in PHP before 4.3.10 allow attackers to bypass safe mode restrictions, cause a denial of service, or execute arbitrary code via (1) a negative offset value to the shmop_write function, (2) an "integer overflow/underflow" in the pack function, or (3) an "integer overflow/underflow" in the unpack function. NOTE: this issue was originally REJECTed by its CNA before publication, but that decision is in active dispute. This candidate may change significantly in the future as a result of further discussion.

The deserialization code in PHP before 4.3.10 and PHP 5.x up to 5.0.2 allows remote attackers to cause a denial of service and execute arbitrary code via untrusted data to the unserialize function that may trigger "information disclosure, double-free and negative reference index array underflow" results.

The php_handle_iff function in image.c for PHP 4.2.2, 4.3.9, 4.3.10 and 5.0.3, as reachable by the getimagesize PHP function, allows remote attackers to cause a denial of service (infinite loop) via a -8 size value.

The php_next_marker function in image.c for PHP 4.2.2, 4.3.9, 4.3.10 and 5.0.3, as reachable by the getimagesize PHP function, allows remote attackers to cause a denial of service (infinite loop) via a JPEG image with an invalid marker value, which causes a negative length value to be passed to php_stream_seek.

PHP 4 (PHP4) allows attackers to cause a denial of service (daemon crash) by using the readfile function on a file whose size is a multiple of the page size.

exif.c in PHP before 4.3.11 allows remote attackers to cause a denial of service (memory consumption and crash) via an EXIF header with a large IFD nesting level, which causes significant stack recursion.

The apache2handler SAPI (sapi_apache2.c) in the Apache module (mod_php) for PHP 5.x before 5.1.0 final and 4.4 before 4.4.1 final allows attackers to cause a denial of service (segmentation fault) via the session.save_path option in a .htaccess file or VirtualHost.

The exif_read_data function in the Exif module in PHP before 4.4.1 allows remote attackers to cause a denial of service (infinite loop) via a malformed JPEG image.
