A vulnerability was discovered and corrected in the Linux 2.6 kernel: The asn1 implementation in the Linux kernel 2.4 before 2.4.36.6 and 2.6 before 2.6.25.5, as used in the cifs and ip_nat_snmp_basic modules; and 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 or execute arbitrary code via a length greater than the working buffer, which can lead to an unspecified overflow; an oid length of zero, which can lead to an off-by-one error; or an indefinite length for a primitive encoding
