+ <title>MIT krb5: Insecure temporary file use in send-pr.sh</title>
+ <synopsis>
+ The send-pr.sh script, included in the mit-krb5 package, is vulnerable to
+ symlink attacks, potentially allowing a local user to overwrite arbitrary
+ files with the rights of the user running the utility.

+ The send-pr.sh script creates 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
+ send-pr.sh is called, 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 MIT krb5 users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge sync
+
+ # emerge -pv "&gt;=app-crypt/mit-krb5-1.3.4-r1"
+ # emerge "&gt;=app-crypt/mit-krb5-1.3.4-r1"</code>
