{"id":"SUSE-SU-2017:2775-1","summary":"Security update for Linux Kernel Live Patch 27 for SLE 12","details":"This update for the Linux Kernel 3.12.61-52_92 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-2017-7645: The NFSv2/NFSv3 server in the nfsd subsystem allowed remote attackers to cause a denial of service (system crash) via a long RPC reply (bsc#1046191).\n","modified":"2026-02-04T03:40:46.360844Z","published":"2017-10-19T08:52:24Z","related":["CVE-2017-1000112","CVE-2017-15274","CVE-2017-7645","CVE-2017-9242"],"upstream":["CVE-2017-1000112","CVE-2017-15274","CVE-2017-7645","CVE-2017-9242"],"references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2017/suse-su-20172775-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1042892"},{"type":"REPORT","url":"https://bugzilla.suse.com/1045327"},{"type":"REPORT","url":"https://bugzilla.suse.com/1046191"},{"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-2017-7645"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2017-9242"}],"affected":[{"package":{"name":"kgraft-patch-SLE12_Update_27","ecosystem":"SUSE:Linux Enterprise Server 12-LTSS","purl":"pkg:rpm/suse/kgraft-patch-SLE12_Update_27&distro=SUSE%20Linux%20Enterprise%20Server%2012-LTSS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2-4.1"}]}],"ecosystem_specific":{"binaries":[{"kgraft-patch-3_12_61-52_92-default":"2-4.1","kgraft-patch-3_12_61-52_92-xen":"2-4.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2017:2775-1.json"}}],"schema_version":"1.7.3"}
