SuSE 11.3 Security Update : OpenSSL (SAT Patch Number 10481)

This script is Copyright (C) 2015 Tenable Network Security, Inc.


Synopsis :

The remote SuSE 11 host is missing one or more security updates.

Description :

OpenSSL has been updated to fix various security issues :

- A Use After Free following d2i_ECPrivatekey error was
fixed which could lead to crashes for attacker supplied
Elliptic Curve keys. This could be exploited over SSL
connections with client supplied keys. (CVE-2015-0209)

- A segmentation fault in ASN1_TYPE_cmp was fixed that
could be exploited by attackers when e.g. client
authentication is used. This could be exploited over SSL
connections. (CVE-2015-0286)

- A ASN.1 structure reuse memory corruption was fixed.
This problem can not be exploited over regular SSL
connections, only if specific client programs use
specific ASN.1 routines. (CVE-2015-0287)

- A X509_to_X509_REQ NULL pointer dereference was fixed,
which could lead to crashes. This function is not
commonly used, and not reachable over SSL methods.
(CVE-2015-0288)

- Several PKCS7 NULL pointer dereferences were fixed,
which could lead to crashes of programs using the PKCS7
APIs. The SSL apis do not use those by default.
(CVE-2015-0289)

- Various issues in base64 decoding were fixed, which
could lead to crashes with memory corruption, for
instance by using attacker supplied PEM data.
(CVE-2015-0292)

- Denial of service via reachable assert in SSLv2 servers,
could be used by remote attackers to terminate the
server process. Note that this requires SSLv2 being
allowed, which is not the default. (CVE-2015-0293)

- A memory leak in the TLS hostname extension was fixed,
which could be used by remote attackers to run SSL
services out of memory. (CVE-2009-5146)
