Chainguard: yazi: security update to 26.9.1-r7

medium Tenable Self-Hosted Container Security Plugin ID 478139

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - russh is a Rust SSH client and server library that includes an SSH agent protocol implementation. Prior to
 0.65.0, the client Session::process_packet path in russh/src/client/encrypted.rs accepts repeated packets
 encoded with russh's private msg::EXT_INFO = 7 before authentication, while the standards-compliant
 EXT_INFO message number 82 does not reach the affected handler. The handle_ext_info function appends every
 parsed extension name to received_extensions without clearing, deduplicating, or bounding the vector. A
 malicious SSH server that deliberately sends private message number 7 can therefore retain an unbounded
 number of attacker-controlled extension names for the session lifetime, causing progressive client memory
 exhaustion. This issue is fixed in version 0.65.0. (CVE-2026-116773)

Solution

Update the yazi library and its related packages to version 26.9.1-r7 or later.
