发布日期: 2023年12月29日
关联CVE: CVE-2023-51385
OpenSSH is the premier connectivity tool for remote login with the SSH protocol. \ It encrypts all traffic to eliminate eavesdropping, connection hijacking, and \ other attacks. In addition, OpenSSH provides a large suite of secure tunneling \ capabilities, several authentication methods, and sophisticated configuration options.
Security Fix(es):
In ssh in OpenSSH before 9.6, OS command injection might occur if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. For example, an untrusted Git repository can have a submodule with shell metacharacters in a user name or host name.(CVE-2023-51385)
