Name of the Vulnerable Software and Affected Versions Cisco IOS XR Software for Cisco Network Convergence System NCS 5500 Series Routers affected versions not specified Description A vulnerability in the gRPC code could allow an unauthenticated, remote attacker to cause a denial of service DoS...

Out-of-bound Writes

gRPC is vulnerable to out-of-bound writes. The vulnerability exists because core/lib/iomgr/error.c causes an heap-based buffer overflow, leading to out-of-bounds writes. This vulnerability may lead to further attacks...

Denial Of Service (DoS)

grpc is vulnerable to denial of service DoS attacks. The library contains a socket leak, meaning socket connections to the server are not closed even after the client side has been terminated. This can allow a malicious user to open multiple sockets to the server and cause it to run out of socket...
