RHSA-2026:1592
Vulnerability from csaf_redhat - Published: 2026-01-29 16:46 - Updated: 2026-03-18 03:17A 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.

RHSA-2026:1595
Vulnerability from csaf_redhat - Published: 2026-01-29 18:34 - Updated: 2026-03-18 03:17A 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.
