The asn1 implementation in (a) the Linux kernel 2.4 before 22.214.171.124 and 2.6 before 126.96.36.199, as used in the cifs and ip_nat_snmp_basic modules; and (b) the gxsnmp package; does not properly validate length values during decoding of ASN.1 BER data, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via (1) a length greater than the working buffer, which can lead to an unspecified overflow; (2) an oid length of zero, which can lead to an off-by-one error; or (3) an indefinite length for a primitive encoding.
