Ubuntu 9.04 : moodle vulnerability (USN-791-2)

Medium Nessus Plugin ID 39517


The remote Ubuntu host is missing a security-related patch.


Christian Eibl discovered that the TeX filter in Moodle allowed any function to be used. An authenticated remote attacker could post a specially crafted TeX formula to execute arbitrary TeX functions, potentially reading any file accessible to the web server user, leading to a loss of privacy. (CVE-2009-1171, MSA-09-0009).

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 moodle package.
