+ <title>OpenSSL, Groff: Insecure tempfile handling</title>
+ <synopsis>
+ groffer, included in the Groff package, and the der_chop script, included
+ in the OpenSSL package, are both vulnerable to symlink attacks, potentially
+ allowing a local user to overwrite arbitrary files with the rights of the
+ user running the utility.

+ <background>
+ <p>
+ OpenSSL is a toolkit implementing the Secure Sockets Layer and
+ Transport Layer Security protocols as well as a general-purpose
+ cryptography library. It includes the der_chop script, which is used to
+ convert DER-encoded certificates to PEM format. Groff (GNU Troff) is a
+ typesetting package which reads plain text mixed with formatting
+ commands and produces formatted output. It includes groffer, a command
+ used to display groff files and man pages on X and tty.
+ </p>
+ </background>
+ <description>
+ <p>
+ groffer and the der_chop script create temporary files in
+ world-writeable directories with predictable names.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ A local attacker could create symbolic links in the temporary files
+ directory, pointing to a valid file somewhere on the filesystem. When
+ groffer or der_chop is executed, this would result in the file being
+ overwritten with the rights of the user running the utility, which
+ could be the root user.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All Groff users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose sys-apps/groff</code>
+ <p>
+ All OpenSSL users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=dev-libs/openssl-0.9.7d-r2"</code>
+ <p>
+ Note: /etc/ssl/misc/der_chop is protected by Portage as a configuration
+ file. Don't forget to use etc-update and overwrite the old version with
+ the new one.
