![]() ![]() Supporting this functionality is a set of session files (timestamps) for each user, stored in `/var/run/sudo-rs/ts`. Only once a configurable timeout has passed will the user have to re-authenticate themselves. Additionally, the default permissions for newly created files generally only allow attackers to read the temporary file, but not write to it.ĬVE-2023-42456 Sudo-rs, a memory safe implementation of sudo and su, allows users to not have to enter authentication at every sudo attempt, but instead only requiring authentication every once in a while in every terminal or process group. ![]() This vulnerability only affects operating systems using a shared temporary directory for all users (typically Linux). If these permissions are overly permissive, attackers with access to the system temporary directory may be able to read and write the file before it is used. As a workaround, you can change your default temporary-file directory using the Java system property java.io.tmpdir, if you’re concerned about this issue but unable to immediately update Jenkins.ĬVE-2023-43497 In Jenkins 2.423 and earlier, LTS 2.414.1 and earlier, uploaded files processed via the Stapler web framework and the Jenkins API MultipartFormDataParser create temporary files in the system temporary directory with the default permissions for newly created files. ![]() Jenkins 2.424, LTS 2.414.2 creates the temporary files in a subdirectory with more restrictive permissions. Additionally, the default permissions for newly created files generally only allow attackers to read the temporary file, but not write to it. CVE-2023-43498 In Jenkins 2.423 and earlier, LTS 2.414.1 and earlier, uploaded files processed via the Stapler web framework and the Jenkins API MultipartFormDataParser create temporary files in the system temporary directory with the default permissions for newly created files. ![]()
