Ubuntu 6.06 LTS / 7.10 / 8.04 LTS : mysql-dfsg-5.0 vulnerabilities (USN-671-1)
Medium Nessus Plugin ID 37299
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionIt was discovered that MySQL could be made to overwrite existing table files in the data directory. An authenticated user could use the DATA DIRECTORY and INDEX DIRECTORY options to possibly bypass privilege checks. This update alters table creation behaviour by disallowing the use of the MySQL data directory in DATA DIRECTORY and INDEX DIRECTORY options. (CVE-2008-2079, CVE-2008-4097 and CVE-2008-4098)
It was discovered that MySQL did not handle empty bit-string literals properly. An attacker could exploit this problem and cause the MySQL server to crash, leading to a denial of service. (CVE-2008-3963).
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 packages.
