The Common Unix Printing System contains a buffer overflow vulnerability. This vulnerability may allow a remote attacker to execute arbitrary code.
The Common Unix Printing System (CUPS) is a printing service used by many Linux and Unix operating systems. CUPS uses a print scheduling process that dispatches print jobs and provides the printer's status to local and remote programs.
The Internet Printing Protocol (IPP) is a standard protocol that defines printing and managing print ques. As specified in RFC 2910, the IPP transport layer consists of an HTTP/1.1 request or response. Section 3.5 of RFC 2910 specifies two different types of tags that can either delimit sections of protocols (delimiter tags) or specify the type of each attribute value (value tags). textWithLanguage tags are defined in section 220.127.116.11 and nameWithLanguage is defined in section 18.104.22.168.
A remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the user running the CUPS server or cause the server to crash. The cupsd daemon may run with root privileges.
Administrators and users should see the systems affected portion of this document for a partial list of affected vendors. Users who compile CUPS from source should see CUPS Article #508: Common UNIX Printing System 1.3.4 for information about obtaining fixed software.
