CVE-2025-1795

Publication date 28 February 2025

Last updated 5 March 2025

Ubuntu priority

Low

Why this priority?

During an address list folding when a separating comma ends up on a folded line and that line is to be unicode-encoded then the separator itself is also unicode-encoded. Expected behavior is that the separating comma remains a plan comma. This can result in the address header being misinterpreted by some mail servers.
