SUSE Security Update: Security update for openssh ______________________________________________________________________________
Announcement ID: SUSE-SU-2018:3776-2 Rating: moderate References: #1091396 #1105010 #1106163 #964336 #982273 Cross-References: CVE-2018-15473 CVE-2018-15919 Affected Products: SUSE Linux Enterprise Server for SAP 12-SP1 ______________________________________________________________________________
An update that solves two vulnerabilities and has three fixes is now available.
Description:
This update for openssh fixes the following issues:
Following security issues have been fixed:
- CVE-2018-15919: Remotely observable behaviour in auth-gss2.c in OpenSSH could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. OpenSSH developers do not want to treat such a username enumeration (or "oracle") as a vulnerability. (bsc#1106163) - CVE-2018-15473: OpenSSH was prone to a user existance oracle vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c. (bsc#1105010)
Also the following security related hardening change was done:
- Remove arcfour,cast,blowfish from list of default ciphers. (bsc#982273)
And the following non-security issues were fixed:
- Stop leaking File descriptors (bsc#964336) - sftp-client.c returns wrong error code upon failure (bsc#1091396)
