## Summary A single root cause in the CLAHE implementation — tile width/height becoming zero — produces two distinct but related unsafe behaviors. Vulnerabilities exists in the `CLAHEImage()` function of ImageMagick’s `MagickCore/enhance.c`. 1. Unsigned integer underflow → out-of-bounds pointer arithmetic (OOB): when `tile_info.height == 0`, the expression `tile_info.height - 1` (unsigned) wraps to a very large value; using that value in pointer arithmetic yields a huge offset and OOB memory access (leading to memory corruption, SIGSEGV, or resource exhaustion). 2. **Division/modulus by zero**: where code performs `... / tile_info.width` or `... % tile_info.height` without re-checking for zero, causing immediate division-by-zero crashes under sanitizers or `abort` at runtime. Both behaviors are triggered by the same invalid tile condition (e.g., CLI exact `-clahe 0x0!` or automatic tile derivation `dim >> 3 == 0` for very small images). --- ## Details ### **Unsigned underflow(ca...

Keycloak is vulnerable to a Denial of Service (DoS) attack due to the default JDK setting that permits Client-Initiated Renegotiation in TLS 1.2. An unauthenticated remote attacker can repeatedly initiate TLS renegotiation requests to exhaust server CPU resources, making the service unavailable. Immediate mitigation is available by setting the `-Djdk.tls.rejectClientInitiatedRenegotiation=true` Java system property in the Keycloak startup configuration.

**Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?** One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

The ComboServlet in Liferay Portal 7.4.0 through 7.4.3.111, and older unsupported versions, and Liferay DXP 2023.Q4.0 through 2023.Q4.2, 2023.Q3.1 through 2023.Q3.5, 7.4 GA through update 92, 7.3 GA through update 35, and older unsupported versions does not limit the number or size of the files it will combine, which allows remote attackers to create very large responses that lead to a denial of service attack via the URL query string.

Vault and Vault Enterprise ("Vault") are vulnerable to an unauthenticated denial of service when processing JSON payloads. This occurs due to a regression from a previous fix for [+HCSEC-2025-24+|https://discuss.hashicorp.com/t/hcsec-2025-24-vault-denial-of-service-though-complex-json-payloads/76393]  which allowed for processing JSON payloads before applying rate limits. This vulnerability, CVE-2025-12044, is fixed in Vault Community Edition 1.21.0 and Vault Enterprise 1.16.27, 1.19.11, 1.20.5, and 1.21.0.

### Impact This vulnerability affects NeuVector deployments only when the `Report anonymous cluster data option` is enabled. When this option is enabled, NeuVector sends anonymous telemetry data to the telemetry server at `https://upgrades.neuvector-upgrade-responder.livestock.rancher.io`. In affected versions, NeuVector does not enforce TLS certificate verification when transmitting anonymous cluster data to the telemetry server. As a result, the communication channel is susceptible to man-in-the-middle (MITM) attacks, where an attacker could intercept or modify the transmitted data. Additionally, NeuVector loads the response of the telemetry server is loaded into memory without size limitation, which makes it vulnerable to a Denial of Service(DoS) attack. The patched version includes the following security improvements: - NeuVector now verifies the telemetry server’s `TLS certificate chain` and `hostname` during the handshake process. This ensures that all telemetry communication...
