CVE-2020-25663 1 Imagemagick 1 Imagemagick 2024-11-21 5.5 Medium
A call to ConformPixelInfo() in the SetImageAlphaChannel() routine of /MagickCore/channel.c caused a subsequent heap-use-after-free or heap-buffer-overflow READ when GetPixelRed() or GetPixelBlue() was called. This could occur if an attacker is able to submit a malicious image file to be processed by ImageMagick and could lead to denial of service. It likely would not lead to anything further because the memory is used as pixel data and not e.g. a function pointer. This flaw affects ImageMagick versions prior to 7.0.9-0.
CVE-2020-25656 4 Debian, Linux, Redhat and 1 more 5 Debian Linux, Linux Kernel, Enterprise Linux and 2 more 2024-11-21 4.1 Medium
A flaw was found in the Linux kernel. A use-after-free was found in the way the console subsystem was using ioctls KDGKBSENT and KDSKBSENT. A local user could use this flaw to get read memory access out of bounds. The highest threat from this vulnerability is to data confidentiality.
CVE-2020-25637 2 Opensuse, Redhat 4 Leap, Advanced Virtualization, Enterprise Linux and 1 more 2024-11-21 6.7 Medium
A double free memory issue was found to occur in the libvirt API, in versions before 6.8.0, responsible for requesting information about network interfaces of a running QEMU domain. This flaw affects the polkit access control driver. Specifically, clients connecting to the read-write socket with limited ACL permissions could use this flaw to crash the libvirt daemon, resulting in a denial of service, or potentially escalate their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
CVE-2020-25632 4 Fedoraproject, Gnu, Netapp and 1 more 12 Fedora, Grub2, Ontap Select Deploy Administration Utility and 9 more 2024-11-21 8.2 High
A flaw was found in grub2 in versions prior to 2.06. The rmmod implementation allows the unloading of a module used as a dependency without checking if any other dependent module is still loaded leading to a use-after-free scenario. This could allow arbitrary code to be executed or a bypass of Secure Boot protections. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

CVE-2020-24698 1 Powerdns 1 Authoritative 2024-11-21 9.8 Critical
An issue was discovered in PowerDNS Authoritative through 4.3.0 when --enable-experimental-gss-tsig is used. A remote, unauthenticated attacker might be able to cause a double-free, leading to a crash or possibly arbitrary code execution. by sending crafted queries with a GSS-TSIG signature.
CVE-2020-24438 3 Adobe, Apple, Microsoft 6 Acrobat, Acrobat Dc, Acrobat Reader and 3 more 2024-11-21 3.3 Low
Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by a use-after-free vulnerability that could result in a memory address leak.

GNU Bison before 3.7.1 has a use-after-free in _obstack_free in lib/obstack.c (called from gram_lex) when a '\0' byte is encountered. NOTE: there is a risk only if Bison is used with untrusted input, and the observed bug happens to cause unsafe behavior with a specific compiler/architecture. The bug report was intended to show that a crash may occur in Bison itself, not that a crash may occur in code that is generated by Bison.
