Notes

Title of the patch: Security update for permissions

Description of the patch: This update for permissions fixes the following issues: Security issues fixed: - CVE-2019-3688: Changed wrong ownership in /usr/sbin/pinger to root:squid which could have allowed a squid user to gain persistence by changing the binary (bsc#1093414). - CVE-2019-3690: Fixed a privilege escalation through untrusted symbolic links (bsc#1150734). Other issue addressed: - Corrected a badly constracted file which could have allowed treating of the shell environment as permissions files (bsc#1097665,bsc#1047247). - Fixed a regression which caused sagmentation fault (bsc#1157198).

Vulnerability from cvelistv5 – Published: 2019-10-07 14:00 – Updated: 2024-09-16 23:01

Title

squid: /usr/sbin/pinger packaged with wrong permission

Summary

The /usr/sbin/pinger binary packaged with squid in SUSE Linux Enterprise Server 15 before and including version 4.8-5.8.1 and in SUSE Linux Enterprise Server 12 before and including 3.5.21-26.17.1 had squid:root, 0750 permissions. This allowed an attacker that compromissed the squid user to gain persistence by changing the binary

CVE-2019-3690 (GCVE-0-2019-3690)

Vulnerability from cvelistv5 – Published: 2019-12-05 15:30 – Updated: 2024-09-16 16:38

Title

chkstat follows untrusted symbolic links

Summary

The chkstat tool in the permissions package followed symlinks before commit a9e1d26cd49ef9ee0c2060c859321128a6dd4230 (please also check the additional hardenings after this fix). This allowed local attackers with control over a path that is traversed by chkstat to escalate privileges.

Severity

6.8 (Medium)


                        
                          CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N
