Unknown vulnerability in classifier code for Linux kernel before 2.2.19 could result in denial of service (hang).

Signedness error in (1) getsockopt and (2) setsockopt for Linux kernel before 2.2.19 allows local users to cause a denial of service.

Unknown vulnerability in sockfilter for Linux kernel before 2.2.19 related to "boundary cases," with unknown impact.

Unknown vulnerabilities in strnlen_user for Linux kernel before 2.2.19, with unknown impact.

The System V (SYS5) shared memory implementation for Linux kernel before 2.2.19 could allow attackers to modify recently freed memory.

Masquerading code for Linux kernel before 2.2.19 does not fully check packet lengths in certain cases, which may lead to a vulnerability.

Certain operations in Linux kernel before 2.2.19 on the x86 architecture copy the wrong number of bytes, which might allow attackers to modify memory, aka "User access asm bug on x86."

Unknown vulnerabilities in the UDP port allocation for Linux kernel before 2.2.19 could allow local users to cause a denial of service (deadlock).

The "mxcsr P4" vulnerability in the Linux kernel before 2.2.17-14, when running on certain Intel CPUs, allows local users to cause a denial of service (system halt).

Vulnerability when Network Address Translation (NAT) is enabled in Linux 2.2.10 and earlier with ipchains, or FreeBSD 3.2 with ipfw, allows remote attackers to cause a denial of service (kernel panic) via a ping -R (record route) command.

IPChains in Linux kernels 2.2.10 and earlier does not reassemble IP fragments before checking the header information, which allows a remote attacker to bypass the filtering rules using several fragments with 0 offsets.

Linux 2.2.3 and earlier allow a remote attacker to perform an IP fragmentation attack, causing a denial of service.

The ugidd RPC interface, by design, allows remote attackers to enumerate valid usernames by specifying arbitrary UIDs that ugidd maps to local user and group names.

Linux 2.1.132 and earlier allows local users to cause a denial of service (resource exhaustion) by reading a large buffer from a random device (e.g. /dev/urandom), which cannot be interrupted until the read has completed.

Bug in AMD K6 processor on Linux 2.0.x and 2.1.x kernels allows local users to cause a denial of service (crash) via a particular sequence of instructions, possibly related to accessing addresses outside of segments.

ICMP information such as (1) netmask and (2) timestamp is allowed from arbitrary hosts.
