# CVE-2010-0734: Denial of service in n/a > Remote attackers can cause application crashes in libcurl via crafted compressed data when zlib decompression is enabled, requiring an upgrade. - **Severity:** Medium 6.8 (`AV:N/AC:M/Au:N/C:P/I:P/A:P`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** Not needed - **Fix available:** Yes - **Published:** 19 Mar 2010 - **Updated:** 7 Aug 2024 - **Also known as:** CURL-CVE-2010-0734, DEBIAN-CVE-2010-0734, DSA-2023-1, GHSA-65fc-r6mj-6v9j, RHSA-2010:0273, RHSA-2010:0329 ## What is CVE-2010-0734? CVE-2010-0734 is a medium-severity denial of service vulnerability in n/a, published on 19 Mar 2010. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description content_encoding.c in libcurl 7.10.5 through 7.19.7, when zlib is enabled, does not properly restrict the amount of callback data sent to an application that requests automatic decompression, which might allow remote attackers to cause a denial of service (application crash) or have unspecified other impact by sending crafted compressed data to an application that relies on the intended data-length limit.

What it is: CVE-2010-0734 is a medium-severity denial of service vulnerability in n/a, published on 19 Mar 2010. 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-2010-0734 in the wild and no public exploit code. Affected product: n/a. 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.
