CVE History

= 3.23.3 LOW2.1 LOW

The CIL compiler in SELinux 3.2 has a use-after-free in __cil_verify_classperms (called from __cil_verify_classpermission and __cil_pre_verify_helper).

The CIL compiler in SELinux 3.2 has a use-after-free in __cil_verify_classperms (called from __verify_map_perm_classperms and hashtab_map).

= -, < 3.33.3 LOW2.1 LOW

The CIL compiler in SELinux 3.2 has a use-after-free in cil_reset_classpermission (called from cil_reset_classperms_set and cil_reset_classperms_list).

= 3.23.3 LOW2.1 LOW

The CIL compiler in SELinux 3.2 has a heap-based buffer over-read in ebitmap_match_any (called indirectly from cil_check_neverallow). This occurs because there is sometimes a lack of checks for invalid statements in an optional block.

all versions3.3 LOW

Context relabeling of filesystems is vulnerable to symbolic link attack, allowing a local, unprivileged malicious entity to change the SELinux context of an arbitrary file to a context with few restrictions. This only happens when the relabeling process is done, usually when taking SELinux state from disabled to enable (permissive or enforcing). The issue was found in policycoreutils 2.5-11.

all versions2.1 LOW

selinux-policy when sysctl fs.protected_hardlinks are set to 0 allows local users to cause a denial of service (SSH login prevention) by creating a hardlink to /etc/passwd from a directory named .config, and updating selinux-policy.

all versions7.2 HIGH

SELinux policycoreutils allows local users to execute arbitrary commands outside of the sandbox via a crafted TIOCSTI ioctl call.
