The ISL Light Remote Desktop (aka com.islonline.isllight.mobile.android) application 2.1.0 for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

Apple Remote Desktop (ARD) for Mac OS X 10.2.8 and later does not drop privileges on the remote machine while installing certain applications, which allows local users to bypass authentication and gain privileges by selecting the icon during installation. NOTE: it could be argued that the issue is not in Remote Desktop itself, but in applications that are installed while using it.

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old.

Hyper-Threading technology, as used in FreeBSD and other operating systems that are run on Intel Pentium and other processors, allows local users to use a malicious thread to create covert channels, monitor the execution of other threads, and obtain sensitive information such as cryptographic keys, via a timing attack on memory cache misses.

FTP servers can allow an attacker to connect to arbitrary ports on machines other than the FTP client, aka FTP bounce.

Local user gains root privileges via buffer overflow in rdist, via lookup() function.

cpio on FreeBSD 2.1.0, Debian GNU/Linux 3.0, and possibly other operating systems, uses a 0 umask when creating files using the -O (archive) or -F options, which creates the files with mode 0666 and allows local users to read or overwrite those files.
