NewStart CGSL MAIN 6.02 : libsepol Multiple Vulnerabilities (NS-SA-2024-0054)

low Nessus Plugin ID 206837

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 6.02, has libsepol packages installed that are affected by multiple vulnerabilities:

 - 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). (CVE-2021-36084)

 - 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). (CVE-2021-36085)

 - 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). (CVE-2021-36086)

 - 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. (CVE-2021-36087)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL libsepol packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
