CVE-2016-8574
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 FRF.15 parser and the ISO CLNS parser. The buffer overflow in the FRF.15 parser occurs in the
frf15 print() function in print-fr.c. Another buffer overflow is caused by improper bounds checking by the ISO CLNS parser in the clnp print() function in print-isoclns.c. 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
frf15 print() and clnp print() functions until a patch is available.Exploit
