Ubuntu 20.04 LTS : Linux kernel (OEM) vulnerabilities (USN-4983-1)

The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4983-1 advisory. Piotr Krysiuk discovered that the eBPF implementation in the Linux kernel did not properly enforce limits for pointer operations. A local attacker could...

CVE-2021-33200: Out-of-bounds Write

kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corne...

Denial Of Service (DoS)

linux-gke-5.3:bionic is vulnerable to denial of service. An issue was discovered in the Linux kernel kernel/bpf/verifier.c has an off-by-one error with a resultant integer underflow affecting out-of-bounds speculation on pointer arithmetic, leading to side-channel attacks that defeat Spectre...

GHSA-4G52-PQCJ-PHVH BLS Signature "Malleability"

Impact 1. BLS signature validation in lotus uses blst library method VerifyCompressed. This method accepts signatures in 2 forms - "serialized", and "compressed", meaning that BLS signatures can be provided as either of 2 unique byte arrays. 2. Lotus block validation functions perform a uniquenes...
