From the Mandriva advisory:
The dba_replace function in PHP 5.2.6 and 4.x allows context-dependent
attackers to cause a denial of service (file truncation) via a key with
the NULL byte. NOTE: this might only be a vulnerability in limited
circumstances in which the attacker can modify or add database entries
but does not have permissions to truncate the file (CVE-2008-7068).
The php_openssl_apply_verification_policy function in PHP before
5.2.11 does not properly perform certificate validation, which has
unknown impact and attack vectors, probably related to an ability to
spoof certificates (CVE-2009-3291).
Unspecified vulnerability in PHP before 5.2.11 has unknown impact
and attack vectors related to missing sanity checks around exif
Unspecified vulnerability in the imagecolortransparent function in
PHP before 5.2.11 has unknown impact and attack vectors related to
an incorrect sanity check for the color index. (CVE-2009-3293)
