Unspecified vulnerability in Sun Solaris 10 and OpenSolaris before snv_96 allows (1) context-dependent attackers to cause a denial of service (panic) via vectors involving creation of a crafted file and use of the sendfilev system call, as demonstrated by a file served by an Apache 2.2.x web server with EnableSendFile configured; and (2) local users to cause a denial of service (panic) via a call to the sendfile system call, as reachable through the sendfilev library.

Stack-based buffer overflow in the cons_options function in options.c in dhcpd in OpenBSD 4.0 through 4.2, and some other dhcpd implementations based on ISC dhcp-2, allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a DHCP request specifying a maximum message size smaller than the minimum IP MTU.
