Title: Juergen Schoenwaelder scotty ntping Buffer Overflow Vulnerability
Severity: HIGH
Description:
ntping is a component of scotty, a Tcl interpreter used to retrieve status and configuration information for TCP/IP networks.
The SUID root ntping utility has been found to contain an exploitable buffer overflow. When ntping is invoked at the command line, the contents of argv[0] are copied to an internal variable without bounds checking. An argument of sufficient length will exceed the size of the destination buffer and will be copied over neighbouring data on the stack. If properly composed, this input can allow a local attacker exploiting this vulnerability to gain root privilege, leading to a complete system compromise.
Affected Products:
- Juergen Schoenwaelder Scotty 2.1.10
- Juergen Schoenwaelder Scotty 2.1.7
- Juergen Schoenwaelder Scotty 2.1.8
