A tampering vulnerability exists in the NuGet Package Manager for Linux and Mac that could allow an authenticated attacker to modify a NuGet package's folder structure, aka 'NuGet Package Manager Tampering Vulnerability'.

Untrusted search path vulnerability in metadata/loader.c in Mono 2.8 and earlier allows local users to gain privileges via a Trojan horse shared library in the current working directory.

The default configuration of ASP.NET in Mono before 2.6.4 has a value of FALSE for the EnableViewStateMac property, which allows remote attackers to conduct cross-site scripting (XSS) attacks, as demonstrated by the __VIEWSTATE parameter to 2.0/menu/menu1.aspx in the XSP sample project.
