Descriptions

The proglottis Go wrapper before 0.1.1 for the GPGME library has a use-after-free, as demonstrated by use for container image pulls by Docker or CRI-O. This leads to a crash or potential code execution during GPG signature verification.

El contenedor Proglottis Go versiones anteriores a 0.1.1 para la biblioteca GPGME, presenta un uso de la memoria previamente liberada, como es demostrado por el uso para las extracciones de imágenes de contenedores para Docker o CRI-O. Esto conlleva a un bloqueo o posible ejecución de código durante una comprobación de la firma GPG.

A use-after-free vulnerability was found in the Go GPGME wrapper library, github.com/proglottis/gpgme. An attacker could use this flaw to crash or cause potential code execution in Go applications that use this library, under certain conditions, during GPG signature verification.
