Comment
This vulnerability makes it easy to perform various denial-of-service attacks against such programs. It is also possible that an attacker could manage a more significant exploit, such as running arbitrary code on the affected system.
The problemcan be used to bypass access restrictions in the web server. Anattacker can view the contents of directories and download filesdirectly rather then receiving their HTML output.
New util-linux packages are available that fix a problem with /bin/login’sPAM implementation. This could, in some non-default setups, cause users toreceive credentials of other users. It is recommended that all usersupdate to the fixed packages.
The initscript distributed with the setserial package (which is not installed or enabled by default) uses predictable temporary file names, and should not be used. setserial-2.17-4 and earlier versions are affected.
