Linux kernel 2.4.x and 2.6.x for x86 allows local users to cause a denial of service (system crash), possibly via an infinite loop that triggers a signal handler with a certain sequence of fsave and frstor instructions, as originally demonstrated using a "crash.c" program.

The e1000 driver for Linux kernel 2.4.26 and earlier does not properly initialize memory before using it, which allows local users to read portions of kernel memory. NOTE: this issue was originally incorrectly reported as a "buffer overflow" by some sources.

The DHCP daemon (DHCPD) for ISC DHCP 3.0.1rc12 and 3.0.1rc13, when compiled in environments that do not provide the vsnprintf function, uses C include files that define vsnprintf to use the less safe vsprintf function, which can lead to buffer overflow vulnerabilities that enable a denial of service (server crash) and possibly execute arbitrary code.

Buffer overflow in the logging capability for the DHCP daemon (DHCPD) for ISC DHCP 3.0.1rc12 and 3.0.1rc13 allows remote attackers to cause a denial of service (server crash) and possibly execute arbitrary code via multiple hostname options in (1) DISCOVER, (2) OFFER, (3) REQUEST, (4) ACK, or (5) NAK messages, which can generate a long string when writing to a log file.
