CVE-2026-15709: Improper Handling of Highly Compressed Data (Data Amplification)

A flaw was found in libsoup's WebSocket implementation when using the permessage-deflate extension. The extension's decompression loop inflate processes data in chunks without enforcing an upper boundary limit on the output buffer size. While libsoup limits the incoming compressed frame size via...

PT-2026-60058

It was discovered that httplib2 performed unbounded decompression of HTTP response bodies when the server used gzip or deflate Content-Encoding. A remote attacker could possibly use this issue to cause httplib2 to use excessive resources, leading to a denial of service...

OpenEXR: integer overflow to OOB write in uncompress_b44_impl()

SummaryThe B44/B44A decoder in OpenEXR reconstructs row pointers into a scratch buffer using int. When the channel width nx is large enough, the product y nx overflows int, causing the row pointer to wrap before the start of the scratch buffer. Subsequent memcpy calls then write decoded pixel...
