A number of vulnerabilities have been found and corrected in PHP: The htmlentities and htmlspecialchars functions in PHP prior to 5.2.5 accepted partial multibyte sequences, which has unknown impact and attack vectors . The output_add_rewrite_var function in PHP prior to 5.2.5 rewrites local forms in which the ACTION attribute references a non-local URL, which could allow a remote attacker to obtain potentially sensitive information by reading the requests for this URL . php-cgi in PHP prior to 5.2.6 does not properly calculate the length of PATH_TRANSLATED, which has unknown impact and attack vectors . The escapeshellcmd API function in PHP prior to 5.2.6 has unknown impact and context-dependent attack vectors related to incomplete multibyte characters . Weaknesses in the GENERATE_SEED macro in PHP prior to 4.4.8 and 5.2.5 were discovered that could produce a zero seed in rare circumstances on 32bit systems and generations a portion of zero bits during conversion due to insufficient precision on 64bit systems . The IMAP module in PHP uses obsolete API calls that allow context-dependent attackers to cause a denial of service via a long IMAP request . In addition, this update also corrects an issue with some float to string conversions. The updated packages have been patched to correct these issues.
