Summary

Details

The signature of a digitally signed S/MIME email message may optionally specify the signature creation date and time. If present, Thunderbird did not compare the signature creation date with the message date and time, and displayed a valid signature despite a date or time mismatch. This could be used to give recipients the impression that a message was sent at a different date or time. This vulnerability affects Thunderbird < 115.6.

Severity

Summary

thunderbird vulnerabilities

Details

Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code.(CVE-2023-6857, CVE-2023-6858, CVE-2023-6859, CVE-2023-6861, CVE-2023-6862, CVE-2023-6863, CVE-2023-6864)

Marcus Brinkmann discovered that Thunderbird did not properly parse a PGP/MIME payload that contains digitally signed text. An attacker could potentially exploit this issue to spoof an email message. (CVE-2023-50762)

Marcus Brinkmann discovered that Thunderbird did not properly compare the signature creation date with the message date and time when using digitally signed S/MIME email message. An attacker could potentially exploit this issue to spoof date and time of an email message. (CVE-2023-50761)

DoHyun Lee discovered that Thunderbird did not properly manage memory when used on systems with the Mesa VM driver. An attacker could potentially exploit this issue to execute arbitrary code. (CVE-2023-6856)

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.
