CVE Page","text":"https://www.suse.com/security/cve/CVE-2019-13272"}],"notes":[{"category":"general","text":"In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.","title":"CVE description"}],"product_status":{"recommended":["SUSE Linux Enterprise Server 12 SP2-LTSS:kgraft-patch-4_4_121-92_104-default-7-2.5.ppc64le","SUSE Linux Enterprise Server 12 SP2-LTSS:kgraft-patch-4_4_121-92_104-default-7-2.5.x86_64","SUSE Linux Enterprise Server 12 SP2-LTSS:kgraft-patch-4_4_121-92_109-default-7-2.5.ppc64le","SUSE Linux Enterprise Server 12 SP2-LTSS:kgraft-patch-4_4_121-92_109-default-7-2.5.x86_64","SUSE Linux Enterprise Server for SAP Applications 12 SP2:kgraft-patch-4_4_121-92_104-default-7-2.5.ppc64le","SUSE Linux Enterprise Server for SAP Applications 12 SP2:kgraft-patch-4_4_121-92_104-default-7-2.5.x86_64","SUSE Linux Enterprise Server for SAP Applications 12 SP2:kgraft-patch-4_4_121-92_109-default-7-2.5.ppc64le","SUSE Linux Enterprise Server for SAP Applications 12 SP2:kgraft-patch-4_4_121-92_109-default-7-2.5.x86_64"]},"references":[{"category":"external","summary":"CVE-2019-13272","url":"https://www.suse.com/security/cve/CVE-2019-13272"},{"category":"external","summary":"SUSE Bug 1140671 for CVE-2019-13272","url":"https://bugzilla.suse.com/1140671"},{"category":"external","summary":"SUSE Bug 1156321 for CVE-2019-13272","url":"https://bugzilla.suse.com/1156321"},{"category":"external","summary":"SUSE Bug 1198122 for CVE-2019-13272","url":"https://bugzilla.suse.com/1198122"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Enterprise Server 12 SP2-LTSS:kgraft-patch-4_4_121-92_104-default-7-2.5.ppc64le","SUSE Linux Enterprise Server 12 SP2-LTSS:kgraft-patch-4_4_121-92_104-default-7-2.5.x86_64","SUSE Linux Enterprise Server 12 SP2-LTSS:kgraft-patch-4_4_121-92_109-default-7-2.5.ppc64le","SUSE Linux Enterprise Server 12 SP2-LTSS:kgraft-patch-4_4_121-92_109-default-7-2.5.x86_64","SUSE Linux Enterprise Server for SAP Applications 12 SP2:kgraft-patch-4_4_121-92_104-default-7-2.5.ppc64le","SUSE Linux Enterprise Server for SAP Applications 12 SP2:kgraft-patch-4_4_121-92_104-default-7-2.5.x86_64","SUSE Linux Enterprise Server for SAP Applications 12 SP2:kgraft-patch-4_4_121-92_109-default-7-2.5.ppc64le","SUSE Linux Enterprise Server for SAP Applications 12 SP2:kgraft-patch-4_4_121-92_109-default-7-2.5.x86_64"]}],"scores":[{"cvss_v3":{"baseScore":7.4,"baseSeverity":"HIGH","vectorString":"CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"products":["SUSE Linux Enterprise Server 12 SP2-LTSS:kgraft-patch-4_4_121-92_104-default-7-2.5.ppc64le","SUSE Linux Enterprise Server 12 SP2-LTSS:kgraft-patch-4_4_121-92_104-default-7-2.5.x86_64","SUSE Linux Enterprise Server 12 SP2-LTSS:kgraft-patch-4_4_121-92_109-default-7-2.5.ppc64le","SUSE Linux Enterprise Server 12 SP2-LTSS:kgraft-patch-4_4_121-92_109-default-7-2.5.x86_64","SUSE Linux Enterprise Server for SAP Applications 12 SP2:kgraft-patch-4_4_121-92_104-default-7-2.5.ppc64le","SUSE Linux Enterprise Server for SAP Applications 12 SP2:kgraft-patch-4_4_121-92_104-default-7-2.5.x86_64","SUSE Linux Enterprise Server for SAP Applications 12 SP2:kgraft-patch-4_4_121-92_109-default-7-2.5.ppc64le","SUSE Linux Enterprise Server for SAP Applications 12 SP2:kgraft-patch-4_4_121-92_109-default-7-2.5.x86_64"]}],"threats":[{"category":"impact","date":"2019-12-11T10:13:46Z","details":"moderate"}],"title":"CVE-2019-13272"}]}
