CVE-2008-1940 (GCVE-0-2008-1940)

Vulnerability from cvelistv5 – Published: 2008-04-24 19:00 – Updated: 2024-08-07 08:41
VLAI
Summary
The RBAC functionality in grsecurity before 2.1.11-2.6.24.5 and 2.1.11-2.4.36.2 does not enforce user_transition_deny and user_transition_allow rules for the (1) sys_setfsuid and (2) sys_setfsgid calls, which allows local users to bypass restrictions for those calls.
Severity

NOTE: the grsecurity developer has disputed this issue, stating that "the function they claim the vulnerability to be in is a trivial function, which can, and has been, easily checked for any supposed vulnerabilities." The developer also cites a past disclosure that was not proven
