PYSEC-2026-3436 zeroconf has unbounded recursion in DNS compression-pointer decoder that allows LAN-local denial of service

Impact DNSIncoming.decodelabelsatoffset recurses once per DNS-name compression pointer RFC 1035 §4.1.4. Pointer cycles and label counts were capped, but the chain length of unique forward pointers was not. A single 3 kB mDNS packet carrying 1500 chained pointers drives the recursion past CPython'...

OpenEXR has a signed 32-bit Overflow in PIZ Decoder Leads to OOB Read/Write

Summaryinternalexrundopiz advances the working wavelet pointer with signed 32-bit arithmetic:cwavbuf += nx ny wcount;Because nx, ny, and wcount are int, a crafted EXR file can make this product overflow and wrap. The next channel then decodes from an incorrect address. The wavelet decode path...

PYSEC-2026-2847 OpenEXR: integer overflow to OOB write in uncompress_b44_impl()

Summary The 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...
