CVE-2026-44378
HighCVSS 7.5Summary
Botan to biblioteka kryptograficzna w C++. Przed wersją 3.12.0, pewne wzorce kodowania o nieokreślonej długości w danych BER mogły powodować kwadratowe zachowanie w parserze, co prowadziło do odmowy usługi. Takie kodowania BER były akceptowane nawet w strukturach, które powinny być kodowane jako DER, co zabrania kodowania o nieokreślonej długości.
Risk Assessment
Podatność ta może prowadzić do odmowy usługi, co może wpłynąć na dostępność aplikacji korzystających z biblioteki Botan. Organizacje mogą być narażone na ataki, które wykorzystują tę lukę do zakłócenia działania systemów.
Recommendation
Zaleca się aktualizację biblioteki Botan do wersji 3.12.0 lub nowszej, aby usunąć tę podatność i zabezpieczyć system przed potencjalnymi atakami.

Original NVD description (English source)
Botan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. Such BER encodings were accepted even in structures which are required to be encoded as DER, which prohibits indefinite length encodings. This vulnerability is fixed in 3.12.0.
