CVE-2026-33809: CWE-400: Uncontrolled Resource Consumption in golang.org/x/image golang.org/x/image/tiff
A maliciously crafted TIFF file can cause image decoding to attempt to allocate up 4GiB of memory, causing either excessive resource consumption or an out-of-memory error.
AI Analysis
Technical Summary
This vulnerability in golang.org/x/image/tiff allows a specially crafted TIFF image to cause the decoder to attempt to allocate an excessive amount of memory (up to 4 GiB). This is classified as CWE-400 (Uncontrolled Resource Consumption). The issue can result in denial of service conditions due to resource exhaustion or application crashes from out-of-memory errors. The CVSS v3.1 base score is 5.3, reflecting a network attack vector with low complexity and no privileges or user interaction required, impacting confidentiality but not integrity or availability.
Potential Impact
An attacker can cause excessive memory allocation during TIFF image decoding, potentially leading to denial of service by exhausting system memory or causing the application to crash. There is no indication of data integrity or availability impact beyond resource exhaustion. No known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch or official fix is available, consider implementing input validation or limiting resource usage when processing TIFF images to mitigate potential impact.
