SuSE 11.3 Security Update : OpenSSL (SAT Patch Number 10470)

high Nessus Plugin ID 81970

Synopsis

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

Description

OpenSSL has been updated to fix various security issues :

- 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)

Solution

Apply SAT patch number 10470.
