## What is CVE-2023-34363?

CVE-2023-34363 is a medium-severity vulnerability in n/a, published on 9 Jun 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

An issue was discovered in Progress DataDirect Connect for ODBC before 08.02.2770 for Oracle. When using Oracle Advanced Security (OAS) encryption, if an error is encountered initializing the encryption object used to encrypt data, the code falls back to a different encryption mechanism that uses an insecure random number generator to generate the private key. It is possible for a well-placed attacker to predict the output of this random number generator, which could lead to an attacker decrypting traffic between the driver and the database server. The vulnerability does not exist if SSL / TLS encryption is used.

Weakness: CWE-338 (Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG))

Check this codebase for CVE-2023-34363 and fix it if it is affected.

What it is: CVE-2023-34363 is a medium-severity vulnerability in n/a, published on 9 Jun 2023. 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-2023-34363 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.
