File openssl-CVE-2014-3505.patch of Package compat-openssl098.29129
commit 1b7024fb69161619855d86b80ae0681ea802e245 Author: Adam Langley <agl@imperialviolet.org> Date: Fri Jun 6 14:19:21 2014 -0700 Avoid double free when processing DTLS packets. The |item| variable, in both of these cases, may contain a pointer to a |pitem| structure within |s->d1->buffered_messages|. It was being freed in the error case while still being in |buffered_messages|. When the error later caused the |SSL*| to be destroyed, the item would be double freed. Thanks to Wah-Teh Chang for spotting that the fix in 1632ef74 was inconsistent with the other error paths (but correct).
