MGASA-2025-0238 - Updated fetchmail package fixes security vulnerability

Publication date: 14 Oct 2025
URL: https://advisories.mageia.org/MGASA-2025-0238.html
Type: security
Affected Mageia releases: 9
CVE: CVE-2025-61962

Description:
It was discovered that fetchmail's SMTP client, when configured to
authenticate, is susceptible to a protocol violation where, when a
trusted but malicious or malfunctioning SMTP server responds to an
authentication request with a "334" code but without a following blank
on the line, it will attempt to start reading from memory address 0x1 to
parse the server's SASL challenge. This event will usually cause a crash
of fetchmail (CVE-2025-61962).
