CVE-2010-3717: n/a vulnerability

CVE-2010-3717: The t3lib_div::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...

The t3lib_div::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 filter_var FILTER_VALIDATE_EMAIL 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.

Security readout for executives and security teams

Older TYPO3 sites can be crashed by sending an extremely long email address to code that validates email input. The impact is availability loss, not data theft, based on the provided sources. The affected TYPO3 branches are very old, so any remaining exposure likely indicates legacy or unsupported infrastructure. Exposure is most likely on legacy TYPO3 4.2, 4.3, or 4.4 installations with public forms or routes that validate attacker-supplied email addresses. Prioritize remediation if legacy TYPO3 is internet-facing or supports revenue, customer service, or security workflows. Otherwise handle through legacy platform retirement planning. Mitigation focus: Upgrade affected TYPO3 branches to the fixed versions or a supported TYPO3 release.; For Debian-managed deployments, review and apply DSA-2121 guidance.; Inventory public email-input paths on legacy TYPO3 sites..
