Summary

Red Hat Security Advisory: xchat security update

Severity

Low

Notes

Topic: An updated xchat package that fixes a stack buffer overflow in the SOCKSv5 proxy code.

Details: X-Chat is a graphical IRC chat client for the X Window System. A stack buffer overflow has been fixed in the SOCKSv5 proxy code. An attacker could create a malicious SOCKSv5 proxy server in such a way that X-Chat would execute arbitrary code if a victim configured X-Chat to use the proxy. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0409 to this issue. Users of X-Chat should upgrade to this erratum package, which contains a backported security patch, and is not vulnerable to this issue.

Detection rules are retrieved from Rulezet.

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.
