{"id":"SUSE-SU-2017:2791-1","summary":"Security update for Linux Kernel Live Patch 21 for SLE 12 SP1","details":"This update for the Linux Kernel 3.12.74-60_64_60 fixes several issues.\n\nThe following security bugs were fixed:\n\n- CVE-2017-15274: security/keys/keyctl.c in the Linux kernel did not consider the case of a NULL payload in conjunction with a nonzero length value, which allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted add_key or keyctl system call (bsc#1045327).\n- CVE-2017-1000112: Updated patch for this issue to be in sync with the other livepatches. Description of the issue: Prevent race condition in net-packet code that could have been exploited by unprivileged users to gain root access (bsc#1052368, bsc#1052311).\n- CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c was too late in checking whether an overwrite of an skb data structure may occur, which allowed local users to cause a denial of service (system crash) via crafted system calls (bsc#1042892).\n- CVE-2017-8890: The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c allowed attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call (bsc#1038564).\n","modified":"2026-02-04T04:16:21.090355Z","published":"2017-10-19T20:21:40Z","related":["CVE-2017-1000112","CVE-2017-15274","CVE-2017-8890","CVE-2017-9242"],"upstream":["CVE-2017-1000112","CVE-2017-15274","CVE-2017-8890","CVE-2017-9242"],"references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2017/suse-su-20172791-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1038564"},{"type":"REPORT","url":"https://bugzilla.suse.com/1042892"},{"type":"REPORT","url":"https://bugzilla.suse.com/1045327"},{"type":"REPORT","url":"https://bugzilla.suse.com/1052311"},{"type":"REPORT","url":"https://bugzilla.suse.com/1052368"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-1000112"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-15274"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-8890"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-9242"}],"affected":[{"package":{"name":"kgraft-patch-SLE12-SP1_Update_21","ecosystem":"SUSE:Linux Enterprise Server for SAP Applications 12 SP1","purl":"pkg:rpm/suse/kgraft-patch-SLE12-SP1_Update_21&distro=SUSE%20Linux%20Enterprise%20Server%20for%20SAP%20Applications%2012%20SP1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2-4.1"}]}],"ecosystem_specific":{"binaries":[{"kgraft-patch-3_12_74-60_64_60-default":"2-4.1","kgraft-patch-3_12_74-60_64_60-xen":"2-4.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2017:2791-1.json"}},{"package":{"name":"kgraft-patch-SLE12-SP1_Update_21","ecosystem":"SUSE:Linux Enterprise Server 12 SP1-LTSS","purl":"pkg:rpm/suse/kgraft-patch-SLE12-SP1_Update_21&distro=SUSE%20Linux%20Enterprise%20Server%2012%20SP1-LTSS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2-4.1"}]}],"ecosystem_specific":{"binaries":[{"kgraft-patch-3_12_74-60_64_60-default":"2-4.1","kgraft-patch-3_12_74-60_64_60-xen":"2-4.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2017:2791-1.json"}}],"schema_version":"1.7.3"}
