SUSE SLED12 / SLES12 Security Update : openssl (SUSE-SU-2018:0925-1)

medium Nessus Plugin ID 109013

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for openssl fixes the following issues :

 - CVE-2018-0739: Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe. (bsc#1087102).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
