CVE-2018-7169 severity moderate: SUSE including 276 source package names (0.9.1:shadow-4.2.1-27.6.1, 1.0.0:shadow-4.2.1-27.6.1, …), 317 product×package rows across 64 product lines (Container caasp/v4/default-http-backend, Container caasp/v4/dnsmasq-nanny, … (64 product lines)): Known Affected 157, Fixed 146, Known Not Affected 14.
An issue was discovered in shadow 4.5. newgidmap (in shadow-utils) is setuid and allows an unprivileged user to be placed in a user namespace where setgroups(2) is permitted. This allows an attacker to remove themselves from a supplementary group, which may allow access to certain filesystem paths if the administrator has used "group blacklisting" (e.g., chmod g-rwx) to restrict access to paths. This flaw effectively reverts a security feature in the kernel (in particular, the /proc/self/setgroups knob) to prevent this sort of privilege escalation.
