php4

It was discovered that the ftp extension of PHP, a server-side,
HTML-embedded scripting language performs insufficient input sanitising,
which permits an attacker to execute arbitrary FTP commands. This
requires the attacker to already have access to the FTP server.

For the oldstable distribution (sarge) this problem has been fixed
in version 4.3.10-21.

For the stable distribution (etch) this problem has been fixed
in version 4.4.4-8+etch3.

For the unstable distribution (sid) this problem won’t be fixed, as php4
will be removed from sid; thus you are strongly advised to migrate to
php5 if you prefer to follow the unstable distribution.

We recommend that you upgrade your PHP packages. Packages for the Sparc
architectures are not yet available, due to problems on the build host. They
will be provided later.
