CGI handling flaw in bozohttpd in NetBSD 6.0 through 6.0.6, 6.1 through 6.1.5, and 7.0 allows remote attackers to execute arbitrary code via crafted arguments, which are handled by a non-CGI aware program.

mail.local in NetBSD versions 6.0 through 6.0.6, 6.1 through 6.1.5, and 7.0 allows local users to change ownership of or append data to arbitrary files on the target system via a symlink attack on the user mailbox.

The fetchurl function in usr.bin/ftp/fetch.c in tnftp, as used in NetBSD 5.1 through 5.1.4, 5.2 through 5.2.2, 6.0 through 6.0.6, and 6.1 through 6.1.5 allows remote attackers to execute arbitrary commands via a | (pipe) character at the end of an HTTP redirect.

On Intel CPUs sysret to non-canonical address causes a fault on the sysret instruction itself after the stack pointer is set to guest value but before the CPL is changed. Systems running on AMD CPUs are not vulnerable to this issue as sysret on AMD CPUs does not generate a fault before the CPL change.

On Xen, a privileged user on a 64 bit PV guest kernel running on a 64 bit hypervisor could use this flaw to escalate privileges to that of the host. Depending on the particular guest kernel it is also possible that non-privileged guest users could also elevate their privileges to that of the host.

For Red Hat Enterprise Linux guests, only privileged guest users can exploit this issue. HVM guests and 32-bit PV guests cannot be used to exploit this issue.

Bodo Möller, Thai Duong and Krzysztof Kotowicz of Google discovered a flaw in the design of SSL version 3.0 that would allow an attacker to calculate the plaintext of secure connections, allowing, for example, secure HTTP cookies to be stolen.
