Subject: Add heartbeat extension bounds check.
|
||||
X-Git-Tag: OpenSSL_1_0_1g~3
|
||||
X-Git-Url: http://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff_plain;h=96db902
|
||||
|
||||
Add heartbeat extension bounds check.
|
||||
|
||||
A missing bounds check in the handling of the TLS heartbeat extension
|
||||
can be used to reveal up to 64k of memory to a connected client or
|
||||
server.
|
||||
|
||||
Thanks for Neel Mehta of Google Security for discovering this bug and to
|
||||
Adam Langley <agl@chromium.org> and Bodo Moeller <bmoeller@acm.org> for
|
||||
preparing the fix (CVE-2014-0160)
