TITLE:
OpenServer auditsh/atcronsh/termsh Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA14892

VERIFY ADVISORY:
http://secunia.com/advisories/14892/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

OPERATING SYSTEM:
SCO OpenServer 5.x
http://secunia.com/product/137/

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. This can be exploited to cause a buffer
overflow via an overly long string in the HOME environment variable.

SOLUTION:
Apply patches.

OpenServer 5.0.6 (requires oss646c or later):
ftp://ftp.sco.com/pub/updates/OpenServer/SCOSA-2005.15/VOL.000.000
