solutions Security update for PHP4 SuSE Linux Maintenance Web (cc880d8594257d1c37f5c5e40549ab75)
Product(s): SUSE CORE 9 for Itanium Processor Family
This update fixes the following security issues:
- A bug that can be exploited by remote attackers to bypass HTML tag filtering (cross-site-scripting prevention) by supplying special tags. These kind of tags should be ignored because they are not valid but they get accepted by some commercial web-browsers.
- A bug that can be exploited by remote attackers by triggering the memory_limit in unsafe states of a PHP execution path to execute arbitrary code.
- Bugs caused by bad array parsing of the user input via GET, POST and COOKIE. One could lead to overwriting variable $_FILES, while the other could expose some pieces of the php memory to the attacker.
- A bug that could disclose php sourcecode in some circumstances.
- Various bugs in the unserializer (CAN-2004-1019).
- A buffer overflow in the exif parser (CAN-2004-1065).
- A bug in readline() that could lead to denial of service.
- A bug in getimagesize() which could lead to denial of service (CAN-2005-0524, CAN-2005-0525)
- Bugs in the exif parser could allow an attacker to execute arbitrary code (CAN-2005-1042) or cause denial of service (CAN-2005-1043)).
- The dlopen() flag for opening php4 modules has been reverted back to RTLD_GLOBAL, as RTDL_LOCAL had some side effects when extensions like php4-unixODBC load their own libraries (unixODBC uses RTLD_GLOBAL).
- Pre-Requires tags of some sub-packages have been tweaked to aid computing the uninstall order.
- performance problems of unserialize() caused by previous security update.
