CVE-2023-29407 is a medium-severity security vulnerability in golang.org/x/image (go), affecting versions < 0.10.0. It is fixed in 0.10.0.
A maliciously-crafted image can cause excessive CPU consumption in decoding. A tiled image with a height of 0 and a very large width can cause excessive CPU consumption, despite the image size (width * height) appearing to be zero.
CVE-2023-29407 has a CVSS score of 6.5 (Medium). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment.
A fixed version is available (0.10.0). Upgrading removes the vulnerable code path.
go
golang.org/x/image (< 0.10.0)golang.org/x/image → 0.10.0 (go)Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter instead of chasing every advisory.
Kodem's runtime-powered SCA identifies whether CVE-2023-29407 is reachable in your applications. Explore open-source security for your team.

CVE-2023-29407 is a medium-severity security vulnerability in golang.org/x/image (go), affecting versions < 0.10.0. It is fixed in 0.10.0.
CVE-2023-29407 has a CVSS score of 6.5 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
golang.org/x/image (go) versions < 0.10.0 is affected.
Yes. CVE-2023-29407 is fixed in 0.10.0. Upgrade to this version or later.
Whether CVE-2023-29407 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
Upgrade golang.org/x/image to 0.10.0 or later.
