https://notcve.org/view.php?id=CVE-2020-27777
15 Dec 2020 — A flaw was found in the way RTAS handled memory accesses in userspace to kernel communication. On a locked down (usually due to Secure Boot) guest system running on top of PowerVM or KVM hypervisors (pseries platform) a root like local user could use this flaw to further increase their privileges to that of a running kernel. Se encontró un fallo en la manera en que RTAS manejaba los accesos a la memoria en el espacio de usuario para la comunicación del kernel.

CVE-2020-27765
https://notcve.org/view.php?id=CVE-2020-27765
04 Dec 2020 — A flaw was found in ImageMagick in MagickCore/segment.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. This would most likely lead to an impact to application availability, but could potentially cause other problems related to undefined behavior. This flaw affects ImageMagick versions prior to 7.0.9-0.

CVE-2020-27771
https://notcve.org/view.php?id=CVE-2020-27771
04 Dec 2020 — In RestoreMSCWarning() of /coders/pdf.c there are several areas where calls to GetPixelIndex() could result in values outside the range of representable for the unsigned char type. The patch casts the return value of GetPixelIndex() to ssize_t type to avoid this bug. This undefined behavior could be triggered when ImageMagick processes a crafted pdf file. Red Hat Product Security marked this as Low severity because although it could potentially lead to an impact to application availability, no specific impa... • https://bugzilla.redhat.com/show_bug.cgi?id=1898290 • CWE-190: Integer Overflow or Wraparound •
