NVD Description

Note: Versions mentioned in the description apply only to the upstream rust-gix-transport package and not the rust-gix-transport package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

gitoxide gix-transport before 0.59.2 fails to filter control characters in git-daemon connect requests, allowing attackers to inject NUL/CR/LF bytes via crafted git URLs. Attackers can inject extra NUL-delimited protocol fields to spoof virtual hosts or inject newlines into daemon requests and logs.
