Ubuntu 6.06 LTS / 6.10 : dovecot vulnerability (USN-387-1)
Medium Nessus Plugin ID 27970
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionDovecot was discovered to have an error when handling its index cache files. This error could be exploited by authenticated POP and IMAP users to cause a crash of the Dovecot server, or possibly to execute arbitrary code. Only servers using the non-default option 'mmap_disable=yes' were vulnerable.
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 dovecot-common, dovecot-imapd and / or dovecot-pop3d packages.
