CVE-2016-7934
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 concerns a buffer overflow in the RTCP parser, specifically in the
rtcp print() function within print-udp.c. Additionally, there's a mention of improper bounds checking by the ISO CLNS parser in the clnp print() function within print-isoclns.c, which could allow a remote attacker to overflow a buffer and potentially execute arbitrary code 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 buffer overflow issue in the RTCP parser and the ISO CLNS parser.
As a temporary workaround, consider restricting access to the
rtcp print() and clnp print() functions until a patch is available.Exploit
