containerd is an open source container runtime.

Templates do not properly consider backticks (`) as Javascript string delimiters, and do not escape them as expected.

A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient to cause a denial of service from a small number of small requests.

A denial of service is possible from excessive resource consumption in net/http and mime/multipart.

Large handshake records may cause panics in crypto/tls.

HTTP and MIME header parsing can allocate large amounts of memory, even when parsing small inputs, potentially leading to a denial of service.

Calling any of the Parse functions on Go source code which contains //line directives with very large line numbers can cause an infinite loop due to integer overflow.

Multipart form parsing can consume large amounts of CPU and memory when processing form inputs containing very large numbers of parts.
