erlang: Erlang OTP ssh: Denial of Service via infinite loop in SFTP channel
A flaw was found in the Erlang OTP ssh Secure Shell component, specifically within its SFTP SSH File Transfer Protocol module. An authenticated SFTP user can exploit this vulnerability by sending specially crafted extended data on an open channel. This action triggers an infinite loop in the...
erlang: Erlang OTP ssh: Information disclosure via symlink resolution in SFTP
A flaw was found in Erlang OTP ssh, specifically within the sshsftpd module. An authenticated SFTP client can exploit this vulnerability by creating a symbolic link symlink inside a restricted directory chroot that points to the root directory. When the client reads this symlink, the sshsftpd...
AZL-92021 CVE-2026-54886 affecting package erlang for versions less than 26.2.5.21-4
Loop with Unreachable Exit Condition 'Infinite Loop' vulnerability in Erlang OTP ssh sshsftpd module allows an authenticated SFTP user to render an SFTP channel permanently unresponsive. The handledata/4 function in sshsftpd contains a catch-all clause that accepts channel data of any type. When...
