Name of the Vulnerable Software and Affected Versions tcpdump versions prior to 4.9.0

Description The issue is related to a buffer overflow in the ISO CLNS parser. This overflow is caused by improper bounds checking in the clnp print() function, located in the print-isoclns.c file. A remote attacker could potentially overflow a buffer by sending an overly long argument, which could lead to the execution of arbitrary code on the system or cause the application to crash.

Recommendations For versions prior to 4.9.0, update to version 4.9.0 or later to resolve the issue. As a temporary workaround, consider restricting access to the clnp print() function until a patch is available.
