Security Bulletin: High Resource Consumption Vulnerability in urllib3 Streaming API Due to Improper Handling of Highly Compressed Data (≤ v2.6.0) affects watsonx.data

Summary A vulnerability in the urllib3 Streaming API versions 1.0 through 2.6.0 allows highly compressed HTTP responses to be decompressed in a way that can consume excessive system resources. When processing compressed data e.g., gzip or brotli, the library may fully decompress a small input int...

Improper Handling of Highly Compressed Data (Data Amplification)

Overview Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data Data Amplification through the JWE decompression that has no upper limit for plaintext size. An attacker can exhaust system memory by sending specially crafted compressed tokens that decompres...

JWCrypto: JWE ZIP decompression bomb

Summary The fix for GHSA-j857-7rvv-vj97 in v1.5.6 is weak in that it does not allow to fully control the amount of plaintext the receiver is willing to deal with and provides just a weak upper bound. The patch limits input token size to 250KB but does not validate the decompressed output size. An...
