Description:
Previous versions of the krb5 packages are vulnerable to local
root privilege escalation caused by not checking the return
code from the setuid() function in several utilities. These
vulnerabilities are not exposed in the default configuration on
rPath Linux, but some rPath Linux users may have configured krb5
to expose the vulnerabilities by enabling the kerberos krsh and
kerberos ftp services, or by making the ksu or v4rcp binaries
setuid root. These vulnerabilities have been resolved in the
new versions of the krb5 packages.
