Security update for openssl SUSE Patch security@suse.de SUSE Security Team openSUSE-SU-2019:1175-1 Final 1 1 2019-04-08T09:12:47Z current 2019-04-08T09:12:47Z 2019-04-08T09:12:47Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for openssl This update for openssl fixes the following issues: Security issues fixed: - The 9 Lives of Bleichenbacher's CAT: Cache Attacks on TLS Implementations (bsc#1117951) - CVE-2019-1559: Fixed OpenSSL 0-byte Record Padding Oracle which under certain circumstances a TLS server can be forced to respond differently to a client and lead to the decryption of the data (bsc#1127080). Other issues addressed: - Fixed IV handling in SHAEXT paths: aes/asm/aesni-sha*-x86_64.pl (bsc#1113975). - Set TLS version to 0 in msg_callback for record messages to avoid confusing applications (bsc#1100078).

If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r (Affected 1.0.2-1.0.2q).
