Описание
In iperf before 3.19.1, iperf_auth.c has an off-by-one error and resultant heap-based buffer overflow.
A flaw was found in iperf3. An off-by-one error in the iperf_auth.c file leads to a heap-based buffer overflow, potentially allowing a network attacker to trigger an application-level denial of service. This overflow occurs during the processing of authentication data. The vulnerability can only be exploited with direct network access.
