Vulnerability from csaf_redhat - Published: 2003-05-22 16:41 - Updated: 2025-11-21 17:25
Summary
Red Hat Security Advisory: balsa security update
Severity
Important
Notes
Topic: Updated Balsa packages are available which fix potential vulnerabilities in the IMAP handling code and in libesmtp.
Details: Balsa is a GNOME email client which includes code from Mutt. A potential buffer overflow exists in Balsa versions 1.2 and higher when parsing mailbox names returned by an IMAP server. It is possible that a hostile IMAP server could cause arbitrary code to be executed by the user running Balsa. Additionally, a buffer overflow in libesmtp (an SMTP library used by Balsa) before version 0.8.11 allows a hostile remote SMTP server to execute arbitrary code via a certain response or cause a denial of service via long server responses. Users of Balsa are recommended to upgrade to these erratum packages which include updated versions of Balsa and libesmtp which are not vulnerable to these issues. Red Hat would like to thank CORE security for discovering the vulnerability, and the Mutt team for providing a patch.
