cryptography: cryptography Subgroup Attack Due to Missing Subgroup Validation for SECT Curves

A validation flaw has been discovered in the python cryptography package. This missing validation allows an attacker to provide a public key point P from a small-order subgroup. This can lead to security issues in various situations, such as the most commonly used signature verification ECDSA and...

firefox: thunderbird: expat: libexpat in Expat allows attackers to trigger large dynamic memory allocations via a small document that is submitted for parsing

A memory amplification vulnerability in libexpat allows attackers to trigger excessive dynamic memory allocations by submitting specially crafted XML input. A small input 250 KiB can cause the parser to allocate hundreds of megabytes, leading to denial-of-service DoS through memory exhaustion...

[SECURITY] Fedora 44 Update: dnsmasq-2.92rel2-9.fc44

Dnsmasq is lightweight, easy to configure DNS forwarder and DHCP server. It is designed to provide DNS and, optionally, DHCP, to a small network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with...

pyzipper has an encryption bypass for small files encrypted using it

Impact A Python operator precedence bug in pyzipper/zipfileaes.py caused the AE-2 format to never be automatically selected during encryption, regardless of file size or compression type. As a result, all encrypted entries are written in AE-1 format unless AE-2 is explicitly forced by the caller...

CVE-2026-42583

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, Lz4FrameDecoder allocates a ByteBuf of size decompressedLength up to 32 MB per block before LZ4 runs. A peer only needs a 21-byte header plus compressedLength payload bytes - 22 bytes if...

Position: AI Security Policy Should Target Systems, Not Models

We present swarm-attack, an open-source adversarial testing framework in which multiple lightweight LLM agents coordinate through shared memory, parallel exploration, and evolutionary optimization. Together, our results demonstrate that both safety bypass of frontier models and software...

Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: ImageMagick (UTSA-2026-016800)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-016800 advisory. ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a heap buffer over-read...

CVE-2026-43399

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. Specifically, a reference leak occurs in the amdgpuuserqwaitioctl function. This issue arises when an I/O control ioctl operation is aborted because the output array provided is insufficient. A local attacker could exploit this to caus...

CVE-2026-43399

CVE-2026-43399 affects the Linux kernel amdgpu driver: a reference leak in amdgpu_userq_wait_ioctl occurs when an ioctl is aborted because the output array is too small. The fix drops references to syncobj and timeline fence during abort, and is cherry-picked from commit 68951e9c3e6bb22396bc42ef2...

Cyberattacks are raising your prices (Lock and Code S07E09)

This week on the Lock and Code podcast… Your prices could be going up because of a little something that one group has started calling the “cyber tax.” Not a “tax” in any regulatory sense of the word, this newly named “cyber tax” is instead a consequence of the growing number of cyberattacks on...
