+ MIT krb5 is the free implementation of the Kerberos network + authentication protocol written by the Massachusetts Institute of + Technology. +

+
+ +

+ The send-pr.sh script creates temporary files in world-writeable + directories with predictable names. +

+
+ +

+ 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. +

+
+ +

+ There is no known workaround at this time. +

+
+ +

+ All MIT krb5 users should upgrade to the latest version: +
