https://notcve.org/view.php?id=CVE-2022-32546
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. Esto conlleva un impacto negativo en la disponibilidad de la aplicación u otros problemas relacionados con un comportamiento indefinido • https://bugzilla.redhat.com/show_bug.cgi?id=2091812 https://github.com/ImageMagick/ImageMagick/commit/f221ea0fa3171f0f4fdf74ac9d81b203b9534c23 https://github.com/ImageMagick/ImageMagick6/commit/29c8abce0da56b536542f76a9ddfebdaab5b2943 https://lists.debian.org/debian-lts-announce/2023/05/msg00020.html • CWE-190: Integer Overflow or Wraparound •
CVE-2022-32547
https://notcve.org/view.php?id=CVE-2022-32547
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. Cuando ImageMagick procesa una entrada diseñada o no confiable, esto causa un impacto negativo en la disponibilidad de la aplicación u otros problemas relacionados con un comportamiento no definido • https://bugzilla.redhat.com/show_bug.cgi?id=2091813 https://github.com/ImageMagick/ImageMagick/commit/eac8ce4d873f28bb6a46aa3a662fb196b49b95d0 https://github.com/ImageMagick/ImageMagick6/commit/dc070da861a015d3c97488fdcca6063b44d47a7b https://lists.debian.org/debian-lts-announce/2023/05/msg00020.html • CWE-704: Incorrect Type Conversion or Cast •
CVE-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 •
CVE-2022-1199
https://notcve.org/view.php?id=CVE-2022-1199
A flaw was found in the Linux kernel. This flaw allows an attacker to crash the Linux kernel by simulating amateur radio from the user space, resulting in a null-ptr-deref vulnerability and a use-after-free vulnerability. Se ha encontrado un fallo en el kernel de Linux. Este fallo permite a un atacante bloquear el kernel de Linux al simular la radioafición desde el espacio de usuario, resultando en una vulnerabilidad null-ptr-deref y una vulnerabilidad de uso de memoria previamente liberada • https://access.redhat.com/security/cve/CVE-2022-1199 https://bugzilla.redhat.com/show_bug.cgi?id=2070694 https://github.com/torvalds/linux/commit/4e0f718daf97d47cf7dec122da1be970f145c809 https://github.com/torvalds/linux/commit/71171ac8eb34ce7fe6b3267dce27c313ab3cb3ac https://github.com/torvalds/linux/commit/7ec02f5ac8a5be5a3f20611731243dc5e1d9ba10 https://security.netapp.com/advisory/ntap-20221228-0006 https://www.openwall.com/lists/oss-security/2022/04/02/5 • CWE-416: Use After Free CWE-476: NULL Pointer Dereference •
CVE-2021-3669 – kernel: reading /proc/sysvipc/shm does not scale with large shared memory segment counts
https://notcve.org/view.php?id=CVE-2021-3669
A flaw was found in the Linux kernel. Measuring usage of the shared memory does not scale with large shared memory segment counts which could lead to resource exhaustion and DoS. Se ha encontrado un fallo en el kernel de Linux. La medición del uso de la memoria compartida no escala con grandes recuentos de segmentos de memoria compartida, lo que podría conllevar a el agotamiento de recursos y el DoS. • https://access.redhat.com/security/cve/CVE-2021-3669 https://bugzilla.redhat.com/show_bug.cgi?id=1980619 https://bugzilla.redhat.com/show_bug.cgi?id=1986473 https://security-tracker.debian.org/tracker/CVE-2021-3669 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
