OESA-2026-3372 (CVE-2026-48829)

Vulnerability from osv_openeuler – Published: 2026-08-13 14:01 – Updated: 2026-08-13 14:01 – Source website

Summary

libgsasl security update

Details

The library includes support for the SASL framework and at least partial support for the CRAM-MD5, EXTERNAL, GSSAPI, ANONYMOUS, PLAIN, SECURID, DIGEST-MD5, LOGIN, and NTLM mechanisms.

Security Fix(es):

In GNU SASL before 2.2.3, DIGEST-MD5 has a NULL pointer dereference affecting both clients and servers, via a known token with no accompanying = character. This occurs in lib/digest-md5/getsubopt.c.(CVE-2026-48829)

GNU SASL before 2.2.4 lacks sanitization of a short challenge in _gsasl_ntlm_client_step in the NTLM client, which could result in memory disclosure via a crafted server.(CVE-2026-56968)

Severity

7.5 (High)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
