Base vector

AV:N/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions tcpdump versions prior to 4.9.3

Description The issue is related to a buffer over-read in the dccp print option() function of the DCCP parser in tcpdump, which can be exploited by a remote attacker to cause a denial of service. The dccp print option() function, located in print-dccp.c, is vulnerable to a buffer over-read, allowing an attacker to potentially disrupt service.

Recommendations For versions prior to 4.9.3, update to version 4.9.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the dccp print option() function in print-dccp.c until a patch is available.
