| Description: | Summary:
The remote host is missing an update for the 'sles11sp4-docker-image' package(s) announced via the SUSE-SU-2016:0778-1 advisory.
Vulnerability Insight:
This rebuild for sles11sp4-docker-image fixes several important security issues done in libraries contained inside, for glibc, openssl, curl and openldap2.
glibc security fixes:
- CVE-2015-7547: A stack-based buffer overflow in getaddrinfo allowed
remote attackers to cause a crash or execute arbitrary code via crafted
and timed DNS responses (bsc#961721)
- CVE-2015-8777: Insufficient checking of LD_POINTER_GUARD environment
variable allowed local attackers to bypass the pointer guarding
protection of the dynamic loader on set-user-ID and set-group-ID
programs (bsc#950944)
- CVE-2015-8776: Out-of-range time values passed to the strftime function
may cause it to crash, leading to a denial of service, or potentially
disclosure information (bsc#962736)
- CVE-2015-8778: Integer overflow in hcreate and hcreate_r could have
caused an out-of-bound memory access. leading to application crashes or,
potentially, arbitrary code execution (bsc#962737)
- CVE-2014-9761: A stack overflow (unbounded alloca) could have caused
applications which process long strings with the nan function to crash
or, potentially, execute arbitrary code. (bsc#962738)
- CVE-2015-8779: A stack overflow (unbounded alloca) in the catopen
function could have caused applications which pass long strings to the
catopen function to crash or, potentially execute arbitrary code.
(bsc#962739)
glibc non-security bugfixes:
- bsc#930721: Accept leading and trailing spaces in getdate input string
- bsc#942317: Recognize power8 platform
- bsc#950944: Always enable pointer guard
- bsc#956988: Fix deadlock in __dl_iterate_phdr openssl security issues fixed:
- 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-2016-0705 (bnc#968047): A double free() bug in the DSA ASN1 parser
code was fixed that could be abused to facilitate a denial-of-service
attack.
- 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 ... [Please see the references for more information on the vulnerabilities]
