UBUNTU-CVE-2026-69248

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In versions 45.0.0 through 48.0.0, if an intermediate constrained CA permits the DNS name foo.example.com, and the leaf certificate has a wildcard in its DNS SAN of .example.com,...

python-cryptography verifier accepts wildcard DNS names allowing escape from permittedSubtrees

Summary If an intermediate constrained CA permits the DNS name foo.example.com, and the leaf certificate has a wildcard in its DNS SAN of .example.com, python-cryptography's verifier accepts which allows escaping outside of the permitted names.

CVE-2026-54496

ZEBRA is a Zcash node written entirely in Rust. Prior to zebrad 5.0.0, halo2gadgets 0.5.0, orchard 0.14.0, zcashprimitives 0.28.0, and zcashd 6.20.0, the variable-base scalar multiplication gadget in halo2gadgets/src/ecc/chip/mul/incomplete.rs used assignadvice for the base point without a copy...

CVE-2026-54496

CVE-2026-54496 affects Zebrad and related crates (halo2_gadgets, orchard, zcash_primitives, zcashd) prior to fixed versions. Root cause: the variable-base scalar multiplication gadget uses assign_advice() to feed the base point in halo2_gadgets—without a copy constraint tying it to the real base—...
