The golang.org/x/crypto/ssh package before 0.0.0-20220314234659-1baeb1ce4c0b for Go allows an attacker to crash a server in certain circumstances involving AddHostKey.

Hello gophers,

Version v0.0.0-20220315160706-3147a52a75dd of golang.org/x/crypto/ssh implements client authentication support for signature algorithms based on SHA-2 for use with existing RSA keys.

Previously, a client would fail to authenticate with RSA keys to servers that reject signature algorithms based on SHA-1. This includes OpenSSH 8.8 by default and—starting today March 15, 2022—github.com for recently uploaded keys.

We are providing this announcement as the error (“ssh: unable to authenticate”) might otherwise be difficult to troubleshoot.

Version v0.0.0-20220314234659-1baeb1ce4c0b (included in the version above) also fixes a potential security issue where an attacker could cause a crash in a golang.org/x/crypto/ssh server under these conditions:

*   The server has been configured by passing a Signer to ServerConfig.AddHostKey.
    
*   The Signer passed to AddHostKey does not also implement AlgorithmSigner.
    
*   The Signer passed to AddHostKey does return a key of type “ssh-rsa” from its PublicKey method.
    

Servers that only use Signer implementations provided by the ssh package are unaffected. This is CVE-2022-27191.

Alla prossima,

Filippo for the Go Security team

**Descriptions****Sensitive parameter values captured in build metadata files by Parameterized Trigger Plugin**

**SECURITY-2185 / CVE-2022-27195**  
**Severity (CVSS):** Low  
**Affected plugin: parameterized-trigger**  
**Description:**

Parameterized Trigger Plugin 2.43 and earlier captures environment variables passed to builds triggered using Parameterized Trigger Plugin, including password parameter values, in their build.xml files. These values are stored unencrypted and can be viewed by users with access to the Jenkins controller file system.

Parameterized Trigger Plugin 2.43.1 does not store captured environment variables in build.xml files.

Existing build.xml files are not automatically updated to remove captured environment variables. They need to be manually cleaned up. To help with this, the plugin will report environment variables stored in build.xml as unloadable data in the Old Data Monitor, that allows discarding this data. Build records are only loaded from disk when needed however, so some builds stored in Jenkins may not immediately appear there.

**Stored XSS vulnerability in Favorite Plugin**

**SECURITY-2557 / CVE-2022-27196**  
**Severity (CVSS):** High  
**Affected plugin: favorite**  
**Description:**

**Agent-to-controller security bypass in Semantic Versioning Plugin**

**SECURITY-2124 / CVE-2022-27201**  
**Severity (CVSS):** High  
**Affected plugin: semantic-versioning-plugin**  
**Description:**

Semantic Versioning Plugin defines a controller/agent message that processes a given file as XML and returns version information. The XML parser is not configured to prevent XML external entity (XXE) attacks, which is only a problem if XML documents are parsed on the Jenkins controller.

Semantic Versioning Plugin 1.13 and earlier does not restrict execution of the controller/agent message to agents, and implements no limitations about the file path that can be parsed. This allows attackers able to control agent processes to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.

This vulnerability is only exploitable in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier. See the LTS upgrade guide.
