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

Description: The issue is related to a buffer overflow in the get next file() function in tcpdump.c, which can be exploited by a remote attacker to gain unauthorized access to information, cause a denial of service, or impact the availability of information. The vulnerability is also described as a heap-based buffer over-read related to aoe print in print-aoe.c and lookup emem in addrtoname.c.

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 the use of the get next file() function until a patch is available. Additionally, be cautious when using command-line arguments to avoid potential exploitation.
