Arch Linux Security Advisory ASA-202103-6
Date : 2021-03-13
CVE-ID : CVE-2021-28041
Package : openssh
Type : arbitrary code execution
Remote : Yes
Link : https://security.archlinux.org/AVG-1657
The package openssh before version 8.5p1-1 is vulnerable to arbitrary
Upgrade to 8.5p1-1.
# pacman -Syu "openssh>=8.5p1-1"
The problem has been fixed upstream in version 8.5p1.
ssh-agent in OpenSSH before 8.5 has a double free that may be relevant
in a few less-common scenarios, such as unconstrained agent-socket
access on a legacy operating system, or the forwarding of an agent to
an attacker-controlled host.
A remote attacker with enough privileges to access the socket of the
forwarding agent might be able to execute arbitrary code.
