OpenStack Swift: s3api middleware enters an infinite loop when processing a truncated aws-chunked PUT request body

In OpenStack Swift before 2.36.2 and 2.37.2, s3api middleware enters an infinite loop when processing a truncated aws-chunked PUT request body. The StreamingInput class repeatedly appends an empty buffer and re-reads, causing the proxy-server worker handling the request to become permanently...

PYSEC-2026-3028 pyquorum: Timing side‑channel in mul_mod

Impact The mulmod function implements multiplication via a binary expansion loop whose execution time depends on the Hamming weight of the second operand the exponent. An attacker who can measure the time of secret‑sharing operations e.g., via a remote service could progressively recover the valu...

PYSEC-2026-2874 Pillow has a PDF Parsing Trailer Infinite Loop (DoS)

Impact An attacker can supply a malicious PDF that causes the process to hang indefinitely, consuming 100% CPU and making the application unresponsive. Patches Patched version: 12.2.0. PdfParser introduced in Pillow 4.2.0 follows Prev pointers in PDF trailers to read cross-reference sections. If ...
