Integer Underflow (Wrap or Wraparound)

Overview Affected versions of this package are vulnerable to Integer Underflow Wrap or Wraparound via the DTLS handshake parsing process. An attacker can cause an out-of-bounds read and potentially disclose sensitive memory or crash the application by sending specially crafted DTLS handshake...

Amazon Linux 2 : ImageMagick, --advisory ALAS2-2026-3278 (ALAS-2026-3278)

The version of ImageMagick installed on the remote host is prior to 6.9.10.97-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2026-3278 advisory. ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-18 a...

Important: ImageMagick

Issue Overview: ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below 7.1.2-189 and 6.9.13-44, when Magick parses an XML file it is possible that a single zero byte is written out of the bounds. This issue has been fixed in versions...

JLSEC-2026-230 AES OCB fails to encrypt some bytes

AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was preexisting in the memory that wasn't written. In the special case of "in place" encryption...
