The beusercreation task in TYPO3 4.2.x before 4.2.15 and 4.3.x before 4.3.7 allows remote authenticated users to gain privileges via a crafted POST request that creates a user account with arbitrary group memberships.

The t3libdiv::validEmail function in TYPO3 4.2.x before 4.2.15, 4.3.x before 4.3.7, and 4.4.x before 4.4.4 does not properly restrict input to filtervar FILTERVALIDATEEMAIL operations in PHP, which allows remote attackers to cause a denial of service (memory consumption and application crash) via a long e-mail address string, a related issue to CVE-2010-3710.

Unspecified vulnerability in the Extension Manager in TYPO3 4.2.x before 4.2.15, 4.3.x before 4.3.7, and 4.4.x before 4.4.4 allows remote authenticated administrators to read and possibly modify arbitrary files via a crafted parameter, a different vulnerability than CVE-2010-3714.
