Assigner: VulDB

Description
A vulnerability has been found in tcpreplay 4.5.1. This vulnerability affects the function mask_cidr6 of the file cidr.c of the component tcpprep. The manipulation leads to heap-based buffer overflow. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. The researcher is able to reproduce this with the latest official release 4.5.1 and the current master branch. The code maintainer cannot reproduce this for 4.5.2-beta1. In his reply the maintainer explains that "[i]n that case, this is a duplicate that was fixed in 4.5.2."

CWE ID Description
CWE-122 A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
CWE-787 The product writes data past the end, or before the beginning, of the intended buffer.
CWE-119 The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a heap-based buffer overflow found in the function mask_cidr6 within the cidr.c file of the tcpprep component in tcpreplay version 4.5.1. It can be triggered remotely, but the attack complexity is high and exploitation is difficult. The issue was fixed in version 4.5.2.


How can this vulnerability impact me? :

The vulnerability can lead to a heap-based buffer overflow, which may cause a denial of service or potentially allow an attacker to execute arbitrary code remotely. However, the attack complexity is high and exploitation is difficult.


What immediate steps should I take to mitigate this vulnerability?

Upgrade tcpreplay to version 4.5.2 or later, as the vulnerability has been fixed in 4.5.2. Avoid using version 4.5.1 or earlier versions that are vulnerable.
