Safari in Apple Mac OS X 10.4 through 10.4.10 allows remote attackers to access local content via file:// URLs.
The VNC server implementation in QEMU, as used by Xen and possibly other environments, allows local users of a guest operating system to read arbitrary files on the host operating system via unspecified vectors related to QEMU monitor mode, as demonstrated by mapping files to a CDROM device. NOTE: some of these details are obtained from third party information.
Content Hub before version 0.0+15.04.20150331-0ubuntu1.0 DBUS API only requires a file path for a content item, it doesn't actually require the confined app have access to the file to create a transfer. This could allow a malicious application using the DBUS API to export file:///etc/passwd which would then send a copy of that file to another app.
cPanel before 68.0.15 allows attackers to read root's crontab file during a short time interval upon enabling or disabling sqloptimizer (SEC-332).
content/html/document/src/nsHTMLDocument.cpp in Mozilla Firefox 3.0.x before 3.0.15 and 3.5.x before 3.5.4 allows user-assisted remote attackers to bypass the Same Origin Policy and read an arbitrary content selection via the document.getSelection function.
Apple GarageBand before 5.1 reconfigures Safari to accept all cookies regardless of domain name, which makes it easier for remote web servers to track users.
Peter's Math Anti-Spam Spinoff plugin for WordPress generates audio CAPTCHA clips by concatenating static audio files without any additional distortion, which allows remote attackers to bypass CAPTCHA protection by reading certain bytes from the generated clip.
