CVE-2015-0235 - glibc gethostbyname
...Tony Finch <dot--at-- at dotat.at>
Subject: [exim] CVE-2015-0235 - glibc gethostbyname remotely exploitable
via exim
Date: Tue, 27 Jan 2015 17:33:45 +0000
"The Exim mail server is exploitable remotely if configured to perform
extra security checks on the HELO and EHLO commands ("helo_verify_hosts"
or "helo_try_verify_hosts" option, or "verify = helo" ACL); we developed
a reliable and fully-functional exploit that bypasses all existing
protections (ASLR, PIE, NX) on 32-bit and 64-bit machines.
