Little Snitch versions 4.0 to 4.0.6 use the SecStaticCodeCheckValidityWithErrors() function without the kSecCSCheckAllArchitectures flag and therefore do not validate all architectures stored in a fat binary. An attacker can maliciously craft a fat binary containing multiple architectures that may cause a situation where Little Snitch treats the running process as having no code signature at all while erroneously indicating that the binary on disk does have a valid code signature. This could lead to users being confused about whether or not the code signature is valid.

Little Snitch version 3.0 through 3.7.3 suffer from a local privilege escalation vulnerability in the installer part. The vulnerability is related to the installation of the configuration file "at.obdev.littlesnitchd.plist" which gets installed to /Library/LaunchDaemons.

Unspecified vulnerability in Objective Development Sharity 3 before 3.5 has unknown impact and attack vectors, related to a "serious security problem."

Multiple unspecified vulnerabilities in Objective Development Sharity before 3.3 allow remote attackers to cause a denial of service (daemon crash) via unspecified vectors.

Multiple PHP remote file inclusion vulnerabilities in WebYep 1.1.9, when register_globals is enabled, allow remote attackers to execute arbitrary PHP code via the webyep_sIncludePath in (1) files in the programm/lib/ directory including (a) WYApplication.php, (b) WYDocument.php, (c) WYEditor.php, (d) WYElement.php, (e) WYFile.php, (f) WYHTMLTag.php, (g) WYImage.php, (h) WYLanguage.php, (i) WYLink.php, (j) WYPath.php, (k) WYPopupWindowLink.php, (l) WYSelectMenu.php, and (m) WYTextArea.php; (2) files in the programm/elements/ directory including (n) WYGalleryElement.php, (o) WYGuestbookElement.php, (p) WYImageElement.php, (q) WYLogonButtonElement.php, (r) WYLongTextElement.php, (s) WYLoopElement.php, (t) WYMenuElement.php, and (u) WYShortTextElement.php; and (3) programm/webyep.php.
