BSD systems SSH format string
| bsd-ssh-format (5637) |  High Risk |
Description:
OpenBSD could allow a local attacker to execute code with gid kmem privileges, due to a vulnerability in the SSH (Secure Shell) program. A local attacker can supply a format string to the printf function to write to a location on the stack. An attacker may be able to use this to gain root level privileges.
Platforms Affected:
- OpenBSD, OpenBSD 2.3
- OpenBSD, OpenBSD 2.4
- OpenBSD, OpenBSD 2.5
- OpenBSD, OpenBSD 2.6
- OpenBSD, OpenBSD 2.7
Remedy:
For OpenBSD:
Apply the patch as listed in OpenBSD Security Advisory, October 6, 2000. See References.
Consequences:
