A heap-buffer overflow was found in the way openjpeg2 handled certain PNG format files. An attacker could use this flaw to cause an application crash or in some cases execute arbitrary code with the permission of the user running such an application.
CWE-122
CVE-2020-27752
A flaw was found in ImageMagick in MagickCore/quantum-private.h. An attacker who submits a crafted file that is processed by ImageMagick could trigger a heap buffer overflow. This would most likely lead to an impact to application availability, but could potentially lead to an impact to data integrity as well. This flaw affects ImageMagick versions prior to 7.0.9-0.
CVE-2020-27251
A heap overflow vulnerability exists within FactoryTalk Linx Version 6.11 and prior. This vulnerability could allow a remote, unauthenticated attacker to send malicious port ranges, which could result in remote code execution.
CVE-2020-27255
A heap overflow vulnerability exists within FactoryTalk Linx Version 6.11 and prior. This vulnerability could allow a remote, unauthenticated attacker to send malicious set attribute requests, which could result in the leaking of sensitive information. This information disclosure could lead to the bypass of address space layout randomization (ASLR).
CVE-2020-25712
A flaw was found in xorg-x11-server before 1.20.10. A heap-buffer overflow in XkbSetDeviceInfo may lead to a privilege escalation vulnerability. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-25664
In WriteOnePNGImage() of the PNG coder at coders/png.c, an improper call to AcquireVirtualMemory() and memset() allows for an out-of-bounds write later when PopShortPixel() from MagickCore/quantum-private.h is called. The patch fixes the calls by adding 256 to rowbytes. An attacker who is able to supply a specially crafted image could affect availability with a low impact to data integrity. This flaw affects ImageMagick versions prior to 6.9.10-68 and 7.0.8-68.
