Title
Cri-o: cri-o: unvalidated image env var causes daemon crash
Summary
A flaw was found in CRI-O's container-creation environment-variable handling
(`mergeEnvs` in `server/utils.go`, consumed by `setupContainerEnvironmentAndWorkdir` in
`server/container_create.go`). When a `CreateContainer` request supplies a `nil` CRI
`Envs` field, CRI-O falls back to using the target OCI image's `config.Env` entries
unfiltered, in contrast to the normal merge path, which validates each entry for a
`key=value` form before use. An OCI image whose `config.Env` contains an entry with no
`=` character (e.g. a bare `NOEQUALS` string) causes CRI-O to split that entry into a
single-element slice and then index its second element, which is out of range. This
triggers an unrecovered Go runtime panic in the `crio` daemon process, crashing it and
terminating the container-runtime service for all workloads on the node until it is
restarted.

Una imagen OCI cuyo \u0027config.Env\u0027 contiene una entrada sin el car\u00e1cter \u0027=\u0027 (por ejemplo, una cadena \u0027NOEQUALS\u0027 simple) hace que CRI-O divida esa entrada en un slice de un solo elemento y luego indexe su segundo elemento, lo cual est\u00e1 fuera de rango. Esto desencadena un p\u00e1nico de tiempo de ejecuci\u00f3n de Go no recuperado en el proceso del demonio \u0027crio\u0027, lo que lo bloquea y termina el servicio de tiempo de ejecuci\u00f3n de contenedores para todas las cargas de trabajo en el nodo hasta que se reinicie."
