CVE-2016-20043 describes a stack buffer overflow vulnerability affecting NRSS RSS Reader versions 0.3.9–0.3.9. This vulnerability allows a local attacker to execute arbitrary code by exploiting the -F parameter. Successful exploitation requires local access and crafting a malicious input exceeding the buffer's capacity. A fix is available; upgrading to a patched version is the recommended mitigation.
Successful exploitation of CVE-2016-20043 allows an attacker with local access to the system running NRSS RSS Reader to execute arbitrary code. This could lead to complete system compromise, including data theft, installation of malware, and denial of service. The attack involves crafting a malicious input with a large padding value (256 bytes) followed by a controlled EIP value, effectively overwriting the return address and hijacking program execution. The blast radius is limited to the system running the vulnerable RSS Reader, but the impact can be severe.
CVE-2016-20043 is not currently listed on KEV or EPSS. The probability of exploitation is considered low due to the requirement for local access and the relatively niche nature of NRSS RSS Reader. Public proof-of-concept exploits are not widely available, but the vulnerability's nature (stack buffer overflow) is well-understood, making exploitation possible for skilled attackers. Published on 2026-03-28.
Systems running NRSS RSS Reader version 0.3.9–0.3.9 are at risk, particularly those where the application is accessible to untrusted users or where local access controls are weak. Users who have deployed NRSS RSS Reader on shared hosting environments or in environments with limited security monitoring are also at increased risk.

The primary mitigation for CVE-2016-20043 is to upgrade to a patched version of NRSS RSS Reader. If upgrading is not immediately feasible, consider limiting the size of the argument passed to the -F parameter. Input validation on the command line can help prevent oversized arguments from being processed. While a WAF is unlikely to be effective in this scenario due to the local nature of the vulnerability, restricting user privileges can limit the potential damage. After upgrade, confirm the vulnerability is resolved by attempting to trigger the overflow with a large -F parameter and verifying that the program does not crash or exhibit unexpected behavior.
