ISC INN 1.7.2

Linux xmonisdn package allows local users to gain root privileges by modifying the IFS or PATH environmental variables.

The STARTTLS implementation in nnrpd in INN 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.

Buffer overflow in INN 2.2.1 and earlier allows remote attackers to cause a denial of service via a maliciously formatted article.
