Description Samuele Negrini 2026-06-30 07:27:26 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A heap out-of-bounds read exists in str2entry_state_information_from_type() (entry.c) in the 389 Directory Server LDIF parser. When importing LDIF with attribute types containing trailing semicolons, the code accesses p[3] through p[6] after finding a semicolon via PL_strchr without verifying sufficient bytes remain in the allocation.

Requires local administrator access via ldif2db import. ASan-proven on instrumented builds; production binaries do not crash due to allocator padding. Present unchanged across all shipped 389-ds-base versions.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
