NVD Description

Note: Versions mentioned in the description apply only to the upstream isync package and not the isync package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

A flaw was found in mbsync in isync 1.4.0 through 1.4.3. Due to an unchecked condition, a malicious or compromised IMAP server could use a crafted mail message that lacks headers (i.e., one that starts with an empty line) to provoke a heap overflow, which could conceivably be exploited for remote code execution.
