CVE-2012-2123: The cap_bprm_set_creds function in security/commoncap.c in the Linux kernel before 3.3.3 does not properly...

Security readout for executives and security teams

This Linux kernel flaw let a local user bypass hardening rules that should apply to privileged executables using file capabilities. The public description highlights disabling ASLR through a parent process. That does not imply remote compromise by itself, but it can weaken defenses and help other local attacks succeed. Exposure is most plausible on older Linux systems running kernels before 3.3.3, or vendor kernels that had not backported the fix. Risk depends on local user access and use of privileged executables implemented with file system capabilities. Treat this as a targeted legacy Linux hardening issue. It is not evidenced as remotely exploitable or actively exploited here, but vulnerable shared systems should be patched because the flaw can reduce exploit resistance for privileged execution paths. Mitigation focus: Apply kernel updates from the relevant Linux distribution vendor.; Confirm vendor advisories include the fcaps personality-flags fix.; Prioritize systems with untrusted local users or shared shell access..
