Description Vincent Danen 2011-08-19 17:05:48 UTC
Stunnel 4.42 fixes a heap corruption vulnerability that may be exploited to possibly perform a remote DoS or remote code execution [1].  The upstream changelog indicates that only 4.40 and 4.41 are affected.

Fedora 16 has a candidate build of 4.41, which would introduce this flaw; it should be updated to 4.42 immediately.
