Mandriva Linux Security Advisory : inn (MDVSA-2012:156)
Medium Nessus Plugin ID 62404
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionA security issue was identified and fixed in ISC INN :
The STARTTLS implementation in INN's NNTP server for readers, nnrpd, before 2.5.3 does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted sessions by sending a cleartext command that is processed after TLS is in place, related to a plaintext command injection attack, a similar issue to CVE-2011-0411 (CVE-2012-3523).
The updated packages have been upgraded to inn 2.5.3 which is not vulnerable to this issue.
SolutionUpdate the affected inews, inn and / or inn-devel packages.
