Denial of Service via reachable assertion

A grpc-swift server is vulnerable to a denial of service attack via a reachable assertion. This was due to incorrect logic when handling GOAWAY frames. The attack is low-effort: it takes very little resources to construct and send the required sequence of frames. The impact on availability is hig...

Uncontrolled Resource Consumption in LengthPrefixedMessageReader

Affected gRPC Swift clients and servers are vulnerable to uncontrolled resource consumption attacks. Excessive memory may be allocated when parsing messages. This can lead to a denial of service...

AZL-26921 CVE-2023-32067 affecting package grpc for versions less than 1.42.0-8

c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service. If a target resolver sends a query, the attacker forges a malformed UDP packet with a length of 0 and returns them to the target resolver. The target resolver erroneously interprets the 0 length as a graceful...

AZL-34782 CVE-2023-32067 affecting package grpc for versions less than 1.62.0-2

AZL-26922 CVE-2023-31130 affecting package grpc for versions less than 1.42.0-11

c-ares is an asynchronous resolver library. aresinetnetpton is vulnerable to a buffer underflow for certain ipv6 addresses, in particular "0::00:00:00/2" was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an administrator to...

AZL-26871 CVE-2023-31147 affecting package grpc for versions less than 1.42.0-10

c-ares is an asynchronous resolver library. When /dev/urandom or RtlGenRandom are unavailable, c-ares uses rand to generate random numbers used for DNS query ids. This is not a CSPRNG, and it is also not seeded by srand so will generate predictable output. Input from the random number generator i...
