CVE-2026-28422 2026-02-27 2.2 Low
Vim is an open source, command line text editor. Prior to version 9.2.0078, a stack-buffer-overflow occurs in `build_stl_str_hl()` when rendering a statusline with a multi-byte fill character on a very wide terminal. Version 9.2.0078 patches the issue.
CVE-2026-28421 2026-02-27 5.3 Medium
Vim is an open source, command line text editor. Versions prior to 9.2.0077 have a heap-buffer-overflow and a segmentation fault (SEGV) exist in Vim's swap file recovery logic. Both are caused by unvalidated fields read from crafted pointer blocks within a swap file. Version 9.2.0077 fixes the issue.
CVE-2026-28420 2026-02-27 4.4 Medium
Vim is an open source, command line text editor. Prior to version 9.2.0076, a heap-based buffer overflow WRITE and an out-of-bounds READ exist in Vim's terminal emulator when processing maximum combining characters from Unicode supplementary planes. Version 9.2.0076 fixes the issue.
CVE-2026-28419 2026-02-27 5.3 Medium
Vim is an open source, command line text editor. Prior to version 9.2.0075, a heap-based buffer underflow exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file where a delimiter appears at the start of a line, Vim attempts to read memory immediately preceding the allocated buffer. Version 9.2.0075 fixes the issue.
CVE-2026-28418 2026-02-27 4.4 Medium
Vim is an open source, command line text editor. Prior to version 9.2.0074, a heap-based buffer overflow out-of-bounds read exists in Vim's Emacs-style tags file parsing logic. When processing a malformed tags file, Vim can be tricked into reading up to 7 bytes beyond the allocated memory boundary. Version 9.2.0074 fixes the issue.

CVE-2026-28231 2026-02-27 N/A
pillow_heif is a Python library for working with HEIF images and plugin for Pillow. Prior to version 1.3.0, an integer overflow in the encode path buffer validation of `_pillow_heif.c` allows an attacker to bypass bounds checks by providing large image dimensions, resulting in a heap out-of-bounds read. This can lead to information disclosure (server heap memory leaking into encoded images) or denial of service (process crash). No special configuration is required — this triggers under default settings. Version 1.3.0 fixes the issue.
CVE-2026-22717 2026-02-27 2.7 Low
Out-of-bound read vulnerability in VMware Workstation 25H1 and below on any platform allows an actor with non-administrative privileges on a guest VM to obtain limited information disclosure from the machine where VMware Workstation is installed.
CVE-2026-25518 1 Cert-manager 1 Cert-manager 2026-02-27 5.9 Medium
cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and using those certificates. In versions from 1.18.0 to before 1.18.5 and from 1.19.0 to before 1.19.3, the cert-manager-controller performs DNS lookups during ACME DNS-01 processing (for zone discovery and propagation self-checks). By default, these lookups use standard unencrypted DNS. An attacker who can intercept and modify DNS traffic from the cert-manager-controller pod can insert a crafted entry into cert-manager's DNS cache. Accessing this entry will trigger a panic, resulting in denial‑of‑service (DoS) of the cert-manager controller. The issue can also be exploited if the authoritative DNS server for the domain being validated is controlled by a malicious actor. This issue has been patched in versions 1.18.5 and 1.19.3.
