DescriptionCVE.org

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.

AnalysisAI

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. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

Technical ContextAI

This vulnerability is classified as Out-of-bounds Read (CWE-125), which allows attackers to read data from memory outside the intended buffer boundaries. 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. Affected products include: Getkovri Kovri, I2Pd. Version information: before 2.17.

RemediationAI

No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate array indices and buffer lengths. Use memory-safe languages. Enable AddressSanitizer during testing.
