Description :

A remote Denial of Service vulnerability was discovered in the
Netfilter IP packet handler. This permited a remote attacker to crash
the machine by sending specially crafted IP packet fragments.
(CVE-2005-0209)

The Netfilter code also contained a memory leak. Certain locally
generated packet fragments are reassembled twice, which caused a
double allocation of a data structure. This could be locally exploited
to crash the machine due to kernel memory exhaustion. (CVE-2005-0210)

Ben Martel and Stephen Blackheath found a remote Denial of Service
vulnerability in the PPP driver. This permited a malicious pppd client
to crash the server machine. (CVE-2005-0384)

Georgi Guninski discovered a buffer overflow in the ATM driver. The
atm_get_addr() function does not validate its arguments sufficiently,
which could permit a local attacker to overwrite large portions of
kernel memory by supplying a negative length argument. This could
eventually lead to arbitrary code execution. (CVE-2005-0531)
