Junos OS: dexp Local Privilege Escalation vulnerabilities in SUID binaries

Summary

A sensitive information disclosure vulnerability in delta-export configuration utility (dexp) of Juniper Networks Junos OS may allow a locally authenticated shell user the ability to create and read database files generated by the dexp utility, including password hashes of local users. Since dexp is shipped with setuid permissions enabled and is owned by the root user, this vulnerability may allow a local privileged user the ability to run dexp with root privileges and access sensitive information in the dexp database.
