+ o Minor bugfixes (pointer arithmetic):
+ - Fix a bug in memarea_alloc() that could have resulted in remote heap
+ write access, if Tor had ever passed an unchecked size to
+ memarea_alloc(). Fortunately, all the sizes we pass to memarea_alloc()
+ are pre-checked to be less than 128 kilobytes. Fixes bug 19150; bugfix
+ on 0.2.1.1-alpha. Bug found by Guido Vranken.

+ o Major bugfixes (key management):
+ - If OpenSSL fails to generate an RSA key, do not retain a dangling pointer
+ to the previous (uninitialized) key value. The impact here should be
+ limited to a difficult-to-trigger crash, if OpenSSL is running an
+ engine that makes key generation failures possible, or if OpenSSL runs
+ out of memory. Fixes bug 19152; bugfix on 0.2.1.10-alpha. Found by
+ Yuan Jochen Kang, Suman Jana, and Baishakhi Ray.
