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.
CVE-2026-2597 1 Leont 1 Crypt::sysrandom::xs 2026-02-27 7.5 High
Crypt::SysRandom::XS versions before 0.010 for Perl is vulnerable to a heap buffer overflow in the XS function random_bytes(). The function does not validate that the length parameter is non-negative. If a negative value (e.g. -1) is supplied, the expression length + 1u causes an integer wraparound, resulting in a zero-byte allocation. The subsequent call to chosen random function (e.g. getrandom) passes the original negative value, which is implicitly converted to a large unsigned value (typically SIZE_MAX). This can result in writes beyond the allocated buffer, leading to heap memory corruption and application crash (denial of service). In common usage, the length argument is typically hardcoded by the caller, which reduces the likelihood of attacker-controlled exploitation. Applications that pass untrusted input to this parameter may be affected.
CVE-2026-27610 2 Parse Community, Parseplatform 2 Parse Dashboard, Parse Dashboard 2026-02-27 5.3 Medium
Parse Dashboard is a standalone dashboard for managing Parse Server apps. In versions 7.3.0-alpha.42 through 9.0.0-alpha.7, the `ConfigKeyCache` uses the same cache key for both master key and read-only master key when resolving function-typed keys. Under specific timing conditions, a read-only user can receive the cached full master key, or a regular user can receive the cached read-only master key. The fix in version 9.0.0-alpha.8 uses distinct cache keys for master key and read-only master key. As a workaround, avoid using function-typed master keys, or remove the `agent` configuration block from your dashboard configuration.
CVE-2026-3281 1 Libvips 1 Libvips 2026-02-27 5.3 Medium
A vulnerability was detected in libvips 8.19.0. This affects the function vips_bandrank_build of the file libvips/conversion/bandrank.c. Performing a manipulation of the argument index results in heap-based buffer overflow. The attack must be initiated from a local position. The exploit is now public and may be used. The patch is named fd28c5463697712cb0ab116a2c55e4f4d92c4088. It is suggested to install a patch to address this issue.
CVE-2026-3282 1 Libvips 1 Libvips 2026-02-27 3.3 Low
A flaw has been found in libvips 8.19.0. This vulnerability affects the function vips_unpremultiply_build of the file libvips/conversion/unpremultiply.c. Executing a manipulation of the argument alpha_band can lead to out-of-bounds read. The attack needs to be launched locally. The exploit has been published and may be used. This patch is called 7215ead1e0cd7d3703cc4f5fca06d7d0f4c22b91. A patch should be applied to remediate this issue.
CVE-2026-3275 1 Tenda 2 F453, F453 Firmware 2026-02-27 8.8 High
A weakness has been identified in Tenda F453 1.0.0.3. This affects the function fromAddressNat of the file /goform/addressNat of the component httpd. Executing a manipulation of the argument entrys can lead to buffer overflow. The attack may be performed from remote. The exploit has been made available to the public and could be used for attacks.
