Ubuntu 4.10 / 5.04 / 5.10 : libapache2-mod-auth-pgsql vulnerability (USN-239-1)
Critical Nessus Plugin ID 20786
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionSeveral format string vulnerabilities were discovered in the error logging handling. By sending specially crafted user names, an unauthenticated remote attacker could exploit this to crash the Apache server or possibly even execute arbitrary code with the privileges of Apache (user 'www-data').
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.
SolutionUpdate the affected libapache2-mod-auth-pgsql package.
