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...

GHSA-FJRM-76X2-C4Q4 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...
