UBUNTU-CVE-2021-43848

h2o is an open source http server. In code prior to the 8c0eca3 commit h2o may attempt to access uninitialized memory. When receiving QUIC frames in certain order, HTTP/3 server-side implementation of h2o can be misguided to treat uninitialized memory as HTTP/3 frames that have been received. Whe...

CVE-2021-43848

CVE-2021-43848 concerns h2o, an open source HTTP server. Affects HTTP/3 support where, from commits 93af138 to d1f0f65, h2o may access uninitialized memory when processing QUIC frames, potentially treating such memory as HTTP/3 frames. In reverse proxy scenarios, an attacker could cause h2o to le...
