SCA: security update for pocketsphinx (GHSA-56r5-2p2f-7cxp)

medium Tenable Cloud Security Plugin ID 444848

Description

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

 - PocketSphinx is a small speech recognizer. Prior to 5.1.1, the trie language-model loaders in
 src/lm/ngram_model_trie.c do not adequately validate boundary conditions in ARPA, DMP, and binary format
 headers, and the acoustic-model loaders in src/mdef.c and src/util/bio.c use sscanf with unbounded string
 fields. Loading an invalid, corrupted, or malicious language or acoustic model can therefore cause stack
 or heap buffer overflows and memory corruption. An attacker who can write to a directory selected by
 POCKETSPHINX_PATH can replace or add a model file that PocketSphinx later loads; users of PocketSphinx
 5prealpha have no backported patch and must migrate to the fixed release. This issue is fixed in version
 5.1.1. (CVE-2026-54559)

Solution

Update the pocketsphinx library and its related packages to version 5.1.1 or later.
