Description Tomas Hoger 2008-05-19 04:06:37 EDT
Apache httpd web server's mod_ssl module linked against OpenSSL >= 0.9.8f can
leak pre-connection memory when connecting client reports support for a
compression algorithm in the initial handshake, causing httpd to run out of
memory after certain amount of SSL connections.

Comment 6 Tomas Hoger 2008-05-19 09:35:17 EDT
According to Joe Orton's investigation, this issue was introduced by the
following OpenSSL patch:

  http://cvs.openssl.org/chngview?cn=15897

which was first included in OpenSSL 0.9.8e.

This issue does not affect versions of httpd / mod_ssl linked with earlier
versions of OpenSSL library.

This issue did not affect mod_ssl packages as shipped in Red Hat Enterprise
Linux 2.1, 3, 4 and 5, and Fedora 7 and 8.  Issue did affect mod_ssl packages in
Fedora 9 (both prefork and worker MPM).
