Impact

An attacker could send a JWE containing compressed data that used large amounts of memory and CPU when decompressed by Decrypt or DecryptMulti. Those functions now return an error if the decompressed data would exceed 250kB or 10x the compressed size (whichever is larger). Thanks to Enze Wang@Alioth and Jianjun Chen@Zhongguancun Lab (@zer0yu and @chenjj) for reporting.
