openssl: fix for CVE-2010-5298
Race condition in the ssl3_read_bytes function in s3_pkt.c in OpenSSL through 1.0.1g, when SSL_MODE_RELEASE_BUFFERS is enabled, allows remote attackers to inject data across sessions or cause a denial of service (use-after-free and parsing error) via an SSL connection in a multithreaded environment. http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2010-5298 (From OE-Core rev: 751f81ed8dc488c500837aeb3eb41ebf3237e10b) Signed-off-by: Yue Tao <Yue.Tao@windriver.com> Signed-off-by: Roy Li <rongqing.li@windriver.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
