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."
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.
