php3 - several

Two vulnerabilities have been discovered in php4 which also apply to
the version of php3 in the stable Debian distribution. The Common
Vulnerabilities and Exposures project identifies the following
problems:

• CAN-2004-0594
  The memory_limit functionality allows remote attackers to execute
  arbitrary code under certain circumstances.

• CAN-2004-0595
  The strip_tags function does not filter null (\0) characters
  within tag names when restricting input to allowed tags, which
  allows dangerous tags to be processed by some web browsers which
  could lead to cross-site scripting (XSS) vulnerabilities.

For the stable distribution (woody) these problems have been fixed in
version 3.0.18-23.1woody2.

For the unstable distribution (sid) these problems have been fixed in
version 3.0.18-27.

We recommend that you upgrade your php3 packages.
