A vulnerability was found in ImageMagick, causing an outside the range of representable values of type 'unsigned long' at coders/pcl.c, when crafted or untrusted input is processed. This leads to a negative impact to application availability or other problems related to undefined behavior. Se ha encontrado una vulnerabilidad en ImageMagick, que causa una salida del rango de valores representables del tipo "unsigned long" en el archivo coders/pcl.c, cuando es procesada una entrada diseñada o no confiable.

In ImageMagick, there is load of misaligned address for type 'double', which requires 8 byte alignment and for type 'float', which requires 4 byte alignment at MagickCore/property.c. Whenever crafted or untrusted input is processed by ImageMagick, this causes a negative impact to application availability or other problems related to undefined behavior. En ImageMagick, se presenta una carga de dirección alineada inapropiadamente para el tipo "double", que requiere una alineación de 8 bytes, y para el tipo "float", que requiere una alineación de 4 bytes, en el archivo MagickCore/property.c.

CVSS: 6.7EPSS: 0%CPEs: 4EXPL: 0CVE-2022-21499 – kernel: possible to use the debugger to write zero into a location of choice
https://notcve.org/view.php?id=CVE-2022-21499
KGDB and KDB allow read and write access to kernel memory, and thus should be restricted during lockdown. An attacker with access to a serial port could trigger the debugger so it is important that the debugger respect the lockdown mode when/if it is triggered. CVSS 3.1 Base Score 6.7 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H). KGDB y KDB permiten el acceso de lectura y escritura a la memoria del kernel, y por lo tanto deben ser restringidos durante el bloqueo. • http://packetstormsecurity.com/files/168191/Kernel-Live-Patch-Security-Notice-LSN-0089-1.html https://git.kernel.org/linus/eadb2f47a3ced5c64b23b90fd2a3463f63726066 https://www.debian.org/security/2022/dsa-5161 https://access.redhat.com/security/cve/CVE-2022-21499 https://bugzilla.redhat.com/show_bug.cgi?id=2084183 • CWE-787: Out-of-bounds Write •
