CVE-2008-1673 - Trickish Affiant


The asn1 implementation in (a) the Linux kernel 2.4 before and 2.6 before 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.
