Notes
Title of the patch: Security update for the Linux Kernel (Live Patch 0 for SLE 15 SP1)
Description of the patch: This update for the Linux Kernel 4.12.14-195 fixes several issues.
The following security issues were fixed:
- CVE-2019-13272: Fixed a privilege escalation from user to root due to improper handling of credentials by leveraging
certain scenarios with a parent-child process relationship (bsc#1156321).
- CVE-2019-10220: Fixed an issue where samba servers could inject relative paths in directory entry lists (bsc#1153108).
Patchnames: SUSE-2019-3248,SUSE-SLE-Module-Live-Patching-15-2019-3248,SUSE-SLE-Module-Live-Patching-15-SP1-2019-3250

"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\u0027s pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.",
