CVE-2016-7992
CVSS v3.1
9.8
Critical
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
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 Classical IP over ATM parser and the ISO CLNS parser. This is caused by improper bounds checking, allowing a remote attacker to overflow a buffer by sending an overly long argument. This 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
print-cip.c and print-isoclns.c functions until a patch is available.
Avoid using the affected API endpoints or functions, such as cip if print() and clnp print(), in the affected versions until the issue is resolved.Exploit
