The remote openSUSE host is missing a security update.
This update for libopenssl0_9_8 fixes the following issues :
- CVE-2016-0800 aka the 'DROWN' attack (bsc#968046):
OpenSSL was vulnerable to a cross-protocol attack that
could lead to decryption of TLS sessions by using a
server supporting SSLv2 and EXPORT cipher suites as a
Bleichenbacher RSA padding oracle.
This update changes the openssl library to :
- Disable SSLv2 protocol support by default.
This can be overridden by setting the environment
variable 'OPENSSL_ALLOW_SSL2' or by using
SSL_CTX_clear_options using the SSL_OP_NO_SSLv2 flag.
Note that various services and clients had already
disabled SSL protocol 2 by default previously.
- Disable all weak EXPORT ciphers by default. These can be
reenabled if required by old legacy software using the
environment variable 'OPENSSL_ALLOW_EXPORT'.
- CVE-2016-0797 (bnc#968048): The BN_hex2bn() and
BN_dec2bn() functions had a bug that could result in an
attempt to de-reference a NULL pointer leading to
crashes. This could have security consequences if these
functions were ever called by user applications with
large untrusted hex/decimal data. Also, internal usage
of these functions in OpenSSL uses data from config
files or application command line arguments. If user
developed applications generated config file data based
on untrusted data, then this could have had security
consequences as well.
- CVE-2016-0799 (bnc#968374) On many 64 bit systems, the
internal fmtstr() and doapr_outch() functions could
miscalculate the length of a string and attempt to
access out-of-bounds memory locations. These problems
could have enabled attacks where large amounts of
untrusted data is passed to the BIO_*printf functions.
If applications use these functions in this way then
they could have been vulnerable. OpenSSL itself uses
these functions when printing out human-readable dumps
of ASN.1 data. Therefore applications that print this
data could have been vulnerable if the data is from
untrusted sources. OpenSSL command line applications
could also have been vulnerable when they print out
ASN.1 data, or if untrusted data is passed as command
line arguments. Libssl is not considered directly

- avoid running OPENSSL_config twice. This avoids breaking
engine loading. (boo#952871, boo#967787)
- fix CVE-2015-3197 (boo#963415)
- SSLv2 doesn't block disabled ciphers
