Description:
Joel Soderberg and Christer Oberg have reported some vulnerabilities in SCO OpenServer, which potentially can be exploited by malicious, local users to gain escalated privileges.
The vulnerabilities are caused due to boundary errors within the auditsh, atcronsh, and termsh programs when handling the HOME environment variable and certain command line arguments. This can be exploited to cause a buffer overflow via an overly long string in the HOME environment variable or via overly long command line arguments.
Solution:
Apply patches.
