Summary
Zserio to framework do serializacji danych strukturalnych w sposób kompaktowy i efektywny. W wersjach przed 2.18.1, odpowiednio przygotowany ładunek o wielkości 4-5 bajtów może wymusić alokacje pamięci do 16 GB, co prowadzi do awarii procesu z błędem OOM (Denial of Service).
Risk Assessment
Podatność ta może prowadzić do awarii usług w organizacji, co skutkuje przerwami w dostępności aplikacji i systemów. Wykorzystanie tej luki może być użyte do przeprowadzenia ataku typu Denial of Service.
Recommendation
Zaleca się aktualizację frameworka Zserio do wersji 2.18.1 lub nowszej, aby usunąć tę podatność i zabezpieczyć system przed potencjalnymi atakami.

Original NVD description (English source)
Zserio is a framework for serializing structured data with a compact and efficient way with low overhead. Prior to 2.18.1, a crafted payload as small as 4-5 bytes can force memory allocations of up to 16 GB, crashing any process with an OOM error (Denial of Service). This vulnerability is fixed in 2.18.1.
