DHCPv6 is the DHCP protocol version for IPv6 networks. A flaw was found in the way the dhcpd daemon processed certain DHCPv6 messages for addresses that had previously been decline ...

Poppler is a Portable Document Format rendering library, used by applications such as Evince. An uninitialized pointer use flaw was discovered in poppler. An attacker could create a malicious PDF file that, when opened, would cause applications that use poppler to crash or, potentially, execute arbitrary code. An array index error was found in the way poppler parsed PostScript Type 1 fonts embe ...

The sudo utility allows system administrators to give certain users the ability to run commands as root. A privilege escalation flaw was found in the way sudo handled the sudoedit pseudo-command. If a local user were authorized by the sudoers file to use this pseudo-command, they could possibly leverage this flaw to execute arbitrary code with the privileges of the root user.
