-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2018.2698 Security update for the Linux Kernel 11 September 2018 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: linux kernel Publisher: SUSE Operating System: SUSE Impact/Access: Increased Privileges -- Existing Account Denial of Service -- Existing Account Access Privileged Data -- Existing Account Resolution: Patch/Upgrade CVE Names: CVE-2018-15471 CVE-2018-10853 Reference: ESB-2018.2436 ESB-2018.2097 Original Bulletin: https://www.suse.com/support/update/announcement/2018/suse-su-20182677-1/ https://www.suse.com/support/update/announcement/2018/suse-su-20182678-1/ Comment: This bulletin contains two (2) SUSE security advisories. - --------------------------BEGIN INCLUDED TEXT-------------------- SUSE Security Update: Security update for the Linux Kernel (Live Patch 1 for SLE 15) ______________________________________________________________________________ Announcement ID: SUSE-SU-2018:2677-1 Rating: important References: #1105026 Cross-References: CVE-2018-15471 Affected Products: SUSE Linux Enterprise Module for Live Patching 15 ______________________________________________________________________________ An update that fixes one vulnerability is now available. Description: This update for the Linux Kernel 4.12.14-25_3 fixes one issue. The following security issue was fixed: - CVE-2018-15471: An issue was discovered in xenvif_set_hash_mapping in drivers/net/xen-netback/hash.c. The Linux netback driver allowed frontends to control mapping of requests to request queues. When processing a request to set or change this mapping, some input validation (e.g., for an integer overflow) was missing or flawed, leading to OOB access in hash handling. A malicious or buggy frontend may cause the (usually privileged) backend to make out of bounds memory accesses, potentially resulting in one or more of privilege escalation, Denial of Service (DoS), or information leaks (bsc#1105026). Patch Instructions: To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". Alternatively you can run the command listed for your product: - SUSE Linux Enterprise Module for Live Patching 15: zypper in -t patch SUSE-SLE-Module-Live-Patching-15-2018-1868=1 SUSE-SLE-Module-Live-Patching-15-2018-1870=1 Package List: - SUSE Linux Enterprise Module for Live Patching 15 (ppc64le x86_64): kernel-livepatch-4_12_14-23-default-3-7.3 kernel-livepatch-4_12_14-23-default-debuginfo-3-7.3 kernel-livepatch-4_12_14-25_3-default-3-2.1 kernel-livepatch-4_12_14-25_3-default-debuginfo-3-2.1 kernel-livepatch-SLE15_Update_0-debugsource-3-7.3 References: https://www.suse.com/security/cve/CVE-2018-15471.html https://bugzilla.suse.com/1105026 - -------------------------------------------------------------------------------- SUSE Security Update: Security update for the Linux Kernel (Live Patch 2 for SLE 15) ______________________________________________________________________________ Announcement ID: SUSE-SU-2018:2678-1 Rating: important References: #1097108 #1103203 #1105026 Cross-References: CVE-2018-10853 CVE-2018-15471 Affected Products: SUSE Linux Enterprise Module for Live Patching 15 ______________________________________________________________________________ An update that solves two vulnerabilities and has one errata is now available.
