VMware Security Advisory - A vulnerability in the udev program did not verify whether a NETLINK message originates from kernel space, which allows local users to gain privileges by sending a NETLINK message from user space. Sudo versions 1.6.9p17 through 1.6.9p19 do not properly interpret a system group in the sudoers file during authorization decisions for a user who belongs to that group, which might allow local users to leverage an applicable sudoers file and gain root privileges by using a sudo command. The redirect implementation in curl and libcurl 5.11 through 7.19.3, when CURLOPT_FOLLOWLOCATION is enabled, accepts arbitrary Location values, which might allow remote HTTP servers to trigger arbitrary requests to intranet servers, read or overwrite arbitrary files by using a redirect to a file: URL, or execute arbitrary commands by using a redirect to an scp: URL.

1.6.9p17 through 1.6.9p19 do not properly interpret a system group
in the sudoers file during authorization decisions for a user who
belongs to that group, which might allow local users to leverage an
applicable sudoers file and gain root privileges by using a sudo
command.

implementation in curl and libcurl 5.11 through 7.19.3, when
CURLOPT_FOLLOWLOCATION is enabled, accepts arbitrary Location
values, which might allow remote HTTP servers to trigger arbitrary
requests to intranet servers, read or overwrite arbitrary files by
using a redirect to a file: URL, or execute arbitrary commands by
using a redirect to an scp: URL.
