# CVE-2011-3365: Security feature bypass in n/a > Remote attackers can spoof certificate common names in KDE security dialogs via rich text rendering flaws, bypassing visual verification. - **Severity:** Medium 4.3 (`AV:N/AC:M/Au:N/C:N/I:P/A:N`) - **Exploited in the wild:** Not known - **Login needed:** Not needed - **Attackable:** Over the internet - **Victim action needed:** A user has to click or open something - **Fix available:** Yes - **Published:** 29 Nov 2011 - **Updated:** 6 Aug 2024 - **Also known as:** GHSA-rcm3-37px-2f83, RHSA-2011:1364, RHSA-2011:1385 ## What is CVE-2011-3365? CVE-2011-3365 is a medium-severity vulnerability in n/a, published on 29 Nov 2011. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link. ### Official description The KDE SSL Wrapper (KSSL) API in KDE SC 4.6.0 through 4.7.1, and possibly earlier versions, does not use a certain font when rendering certificate fields in a security dialog, which allows remote attackers to spoof the common name (CN) of a certificate via rich text.

What it is: CVE-2011-3365 is a medium-severity vulnerability in n/a, published on 29 Nov 2011. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link. Exploitation: There is no known exploitation of CVE-2011-3365 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.
