openSUSE Leap 15.0: 2018:2592-1 Moderate: libressl Timing Leak

This update for libressl to version 2.8.0 fixes the following issues:

Security issues fixed:

- CVE-2018-12434: Avoid a timing side-channel leak when generating DSA and

ECDSA signatures. (boo#1097779)

- Reject excessively large primes in DH key generation.

Other bugs fixed:

- Fixed a pair of 20+ year-old bugs in X509_NAME_add_entry.

- Tighten up checks for various X509_VERIFY_PARAM functions, 'poisoning'

parameters so that an unverified certificate cannot be used if it fails

verification.

- Fixed a potential memory leak on failure in ASN1_item_digest.

- Fixed a potential memory alignment crash in asn1_item_combine_free.

- Removed unused SSL3_FLAGS_DELAY_CLIENT_FINISHED and

SSL3_FLAGS_POP_BUFFER flags in write path, simplifying IO paths.

- Removed SSL_OP_TLS_ROLLBACK_BUG buggy client workarounds.

- Added const annotations to many existing APIs from OpenSSL, making

interoperability easier for downstream applications.
