ISS X-Force Database: linux-kernel-ber-decoder-bo(42921): Linux kernel BER decoder buffer overflow

Linux kernel BER decoder buffer overflow

linux-kernel-ber-decoder-bo (42921)

High Risk

Description:

Linux kernel is vulnerable to a buffer overflow, caused by improper bounds checking by the ASN.1 BER decoder of the cifs and ip_nat_snmp_basic modules. By sending specially-crafted BER encoded data, a remote attacker from within the local network could overflow a buffer and execute arbitrary code on the system or cause the application to crash.

BID-29589: Linux Kernel BER Decoding Remote Buffer Overflow Vulnerability
CVE-2008-1673: The asn1 implementation in (a) 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 (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.
