Total proxychains-ng_project CVEs: 2
Earliest CVE date: 21 Sep 2017, 16:29 UTC
Latest CVE date: 18 Dec 2025, 22:15 UTC
Latest CVE reference: CVE-2025-34451
30-day Count (Rolling): 1
365-day Count (Rolling): 1
Calendar-based Variation
Calendar-based Variation compares a fixed calendar period (e.g., this month versus the same month last year), while Rolling Growth Rate uses a continuous window (e.g., last 30 days versus the previous 30 days) to capture trends independent of calendar boundaries.
Month Variation (Calendar): 0%
Year Variation (Calendar): 0%
Month Growth Rate (30-day Rolling): 0.0%
Year Growth Rate (365-day Rolling): 0.0%
Average CVSS: 3.6
Max CVSS: 7.2

These are the five CVEs with the highest CVSS scores for proxychains-ng_project, sorted by severity first and recency.
rofl0r/proxychains-ng versions up to and including 4.17 and prior to commit cc005b7 contain a stack-based buffer overflow vulnerability in the function proxy_from_string() located in src/libproxychains.c. When parsing crafted proxy configuration entries containing overly long username or password fields, the application may write beyond the bounds of fixed-size stack buffers, leading to memory corruption or crashes. This vulnerability may allow denial of service and, under certain conditions, could be leveraged for further exploitation depending on the execution environment and applied mitigations.
Untrusted search path vulnerability in ProxyChains-NG before 4.9 allows local users to gain privileges via a Trojan horse libproxychains4.so library in the current working directory, which is referenced in the LD_PRELOAD path.
