# CVE-2008-5077: Security feature bypass in n/a > Remote attackers can bypass SSL/TLS certificate validation for DSA and ECDSA keys by exploiting improper return value checks in OpenSSL. - **Severity:** Medium 5.8 (`AV:N/AC:M/Au:N/C:N/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:** 7 Jan 2009 - **Updated:** 7 Aug 2024 - **Also known as:** DEBIAN-CVE-2008-5077, DSA-1701-1, GHSA-5fwv-px3v-6qxv, RHSA-2009:0004 ## What is CVE-2008-5077? CVE-2008-5077 is a medium-severity vulnerability in Openssl Openssl, published on 7 Jan 2009. An attacker can exploit it over the internet without logging in, with no action from the victim. ### Official description OpenSSL 0.9.8i and earlier does not properly check the return value from the EVP_VerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys.

What it is: CVE-2008-5077 is a medium-severity vulnerability in Openssl Openssl, published on 7 Jan 2009. 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-2008-5077 in the wild and no public exploit code. Affected product: Openssl Openssl. 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.
