medium Tenable Cloud Security Plugin ID 461375

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - OpenLDAP Lightning Memory-Mapped Database (LMDB) versions up to and including 0.9.14, prior to commit
 8e1fda8, contain a heap buffer underflow in the readline() function of mdb_load. When processing malformed
 input containing an embedded NUL byte, an unsigned offset calculation can underflow and cause an out-of-
 bounds read of one byte before the allocated heap buffer. This can cause mdb_load to crash, leading to a
 limited denial-of-service condition. (CVE-2026-22185)

Solution

Update the lmdb library and its related packages to version 0.9.31-1+e1 or later.
