FKIE_CVE-2017-17066

Vulnerability from fkie_nvd - Published: 2017-12-05 09:29 - Updated: 2026-05-13 00:24
Severity ?
7.5 (High) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
The (1) i2pd before 2.17 and (2) kovri pre-alpha implementations of the I2P routing protocol do not properly handle Garlic DeliveryTypeTunnel packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading sensitive router memory, aka the GarlicRust bug.
