Summary

Red Hat Security Advisory: spamassassin security update

Severity

Important

Notes

Topic: Updated spamassassin packages that fix a security issue are now available for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team.

Details: SpamAssassin provides a way to reduce unsolicited commercial email (spam) from incoming email. A flaw was found in the way SpamAssassin processes HTML email containing URIs. A carefully crafted mail message could cause SpamAssassin to consume significant resources. If a number of these messages are sent, this could lead to a denial of service, potentially delaying or preventing the delivery of email. (CVE-2007-0451) Users of SpamAssassin should upgrade to these updated packages which contain version 3.1.8 which is not vulnerable to these issues.

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.
