BIT-PILLOW-2026-96642 Pillow: TarIO negative size field causes infinite CPU-spin loop

Pillow is a Python imaging library. Prior to 13.0.0, the TarIO initializer in src/PIL/TarIO.py accepts a negative octal member size and computes a backward seek that returns to the same 512-byte header. When the requested member name does not match, the parser repeatedly reads that header, consum...

GHSA-3J72-P6QG-6XP7 Pillow: TarIO negative size field causes infinite CPU-spin loop

Summary TarIO.init does not check that a tar header's size field is positive. A crafted header with a negative size makes it seek backward onto itself. This causes an infinite loop that uses 100% CPU and never returns. Details TarIO.init reads 512-byte tar headers one at a time, looking for a...

CVE-2026-96642

The Pillow Python imaging library is vulnerable to an infinite CPU-spin loop in the TarIO initializer (located in src/PIL/TarIO.py) in versions prior to 13.0.0 . The root cause is the acceptance of a negative octal member size , which triggers a backward seek that returns to the same 512-byte hea...

Bytedeco JavaCV numerical error vulnerability

Bytedeco JavaCV versions prior to 1.5.14 have a numerical error vulnerability. This vulnerability stems from IPCameraFrameGrabber not checking for overflow or limiting the Content-Length when doubling the 32-bit buffer capacity. Malicious camera endpoints or tampered plaintext streams can return ...
