SUSE Security Update: Security update for the Linux Kernel (Live Patch 20 for SLE 12 SP3) ______________________________________________________________________________
Announcement ID: SUSE-SU-2018:3867-1 Rating: important References: #1107832 Cross-References: CVE-2018-14633 Affected Products: SUSE Linux Enterprise Live Patching 12-SP3 ______________________________________________________________________________
An update that fixes one vulnerability is now available.
Description:
This update for the Linux Kernel 4.4.156-94_64 fixes one issue.
The following security issue was fixed:
- CVE-2018-14633: A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely (bsc#1107832).
