CVE-2016-7931
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 MPLS parser and the ISO CLNS parser. Specifically, the
mpls print() function in print-mpls.c and the clnp print() function in print-isoclns.c are affected. This could allow a remote attacker to overflow a buffer and execute arbitrary code on the system or cause the application to crash by sending an overly long argument.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
mpls print() and clnp print() functions until a patch is available. Avoid using the affected API endpoints or functions with overly long arguments until the issue is resolved.Exploit
