# CVE-2019-14906: Memory corruption in SDL > Heap-based buffer overflow in SDL allows attackers to execute code or crash applications via malicious BMP files. - **Severity:** High 8.1 (`CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 7 Jan 2020 - **Updated:** 5 Aug 2024 - **Also known as:** GHSA-2w82-mm6w-3vc9, RHSA-2019:4024 ## What is CVE-2019-14906? CVE-2019-14906 is a high-severity memory corruption vulnerability in Redhat Enterprise Linux, published on 7 Jan 2020. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description A flaw was found with the RHSA-2019:3950 erratum, where it did not fix the CVE-2019-13616 SDL vulnerability. This issue only affects Red Hat SDL packages, SDL versions through 1.2.15 and 2.x through 2.0.9 has a heap-based buffer overflow flaw while copying an existing surface into a new optimized one, due to a lack of validation while loading a BMP image, is possible. An application that uses SDL to parse untrusted input files may be vulnerable to this flaw, which could allow an attacker to make the application crash or execute code.

What it is: CVE-2019-14906 is a high-severity memory corruption vulnerability in Redhat Enterprise Linux, published on 7 Jan 2020. An attacker can exploit it over the internet without logging in, with no action from the victim. Exploitation: There is no known exploitation of CVE-2019-14906 in the wild and no public exploit code. Affected product: Redhat Enterprise Linux. No package-level version data is available, so check the vendor advisory linked from the reference page. Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
