Denial of Service Vulnerability in Linux Kernel's ASN.1 BER Decoder

CVE-2016-2053 · MEDIUM Severity

AV:L/AC:M/AU:N/C:N/I:N/A:C

The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel before 4.3 allows attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c.
