Ubuntu 10.04 LTS / 12.04 LTS / 12.10 / 13.04 : php5 vulnerability (USN-1937-1)

Medium Nessus Plugin ID 69797


The remote Ubuntu host is missing one or more security-related patches.


It was discovered that PHP did not properly handle certificates with NULL characters in the Subject Alternative Name field. An attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected packages.
