Descriptions

Integer overflow in lib/asn1_decoder.c in the Linux kernel before 4.6 allows local users to gain privileges via crafted ASN.1 data.

Desbordamiento de entero en lib/asn1_decoder.c en el kernel de Linux en versiones anteriores a 4.6 permite a usuarios locales obtener privilegios a través de datos ASN.1 manipulados.

A flaw was found in the way the Linux kernel's ASN.1 DER decoder processed certain certificate files with tags of indefinite length. A local, unprivileged user could use a specially crafted X.509 certificate DER file to crash the system or, potentially, escalate their privileges on the system.
