CVE-2017-5484
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 buffer overflows in tcpdump, specifically in the ATM parser and the ISO CLNS parser. The ATM parser has a buffer overflow in the
sig print() function, while the ISO CLNS parser has improper bounds checking in the clnp print() function. 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
print-atm.c and print-isoclns.c functions until a patch is available. Avoid using the clnp print() function in the affected API endpoint until the issue is resolved.Exploit
