Title: SCO Unixware pkginstall/pkgcat Buffer Overflow Vulnerabilities
Severity: LOW
Description:
It is possible to view the entries in /etc/shadow through exploiting a buffer overflow in pkgcat and pkginstall. Though neither of these binaries are setuid, the dacread permissions which are granted in /etc/security/tcb/privs give them the ability read /etc/shadow. When the oversized buffer data is passed to the programs as argv[1], the stack will be corrupted and it is possible to spawn a program which would "cat" /etc/shadow with the dacread privs.
Affected Products:
- SCO Unixware 7.1.0
