Memory Allocation with Excessive Size Value

Overview Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value via the deserialization process. An attacker can cause excessive memory allocation leading to process crashes by submitting a specially crafted payload. Remediation Upgrade...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the readBytes or readString functions in BitStreamReader when the setBitPosition process receives an overflowed value, bypassing bounds checks. An attacker can cause a segmentation fault and potentiall...

GHSA-CWQ5-8PVQ-J65J Zserio Runtime: Integer Overflow in BitStreamReader and Unbounded Memory Allocation in Deserialization

Summary Unbounded Memory Allocation all platforms 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. Affected code C++: - cpp/runtime/src/zserio/Array.h line 1029 — mrawArray.reservereadLength with uncheck...
