# CVE-2017-14737: Information disclosure in n/a

> A local attacker can recover RSA secret keys via a cache-based side channel in the Botan library, requiring an upgrade to secure versions.

- **Severity:** Medium 5.5 (`CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N`)
- **Exploited in the wild:** Not known
- **Login needed:** Any signed-in user
- **Attackable:** Local or same network only
- **Victim action needed:** Not needed
- **Fix available:** Yes
- **Published:** 26 Sep 2017
- **Updated:** 5 Aug 2024
- **Also known as:** DLA-1125-1, DLA-2812-1, GHSA-xr8r-2cxg-2rgp, MGASA-2017-0422, SUSE-SU-2017:2855-1, UBUNTU-CVE-2017-14737

## What is CVE-2017-14737?

CVE-2017-14737 is a medium-severity vulnerability in Debian Debian Linux, published on 26 Sep 2017. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

A cryptographic cache-based side channel in the RSA implementation in Botan before 1.10.17, and 1.11.x and 2.x before 2.3.0, allows a local attacker to recover information about RSA secret keys, as demonstrated by CacheD. This occurs because an array is indexed with bits derived from a secret key.

## Which versions are affected by CVE-2017-14737?

It affects 2 products.


| Package | Ecosystem | Affected | Fixed in |
| --- | --- | --- | --- |
| `Botan` | SUSE:Linux Enterprise Software Development Kit 12 SP2 | All versions | 1.10.9-4.3.1 |

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2017-14737 and fix it if it is affected.

What it is: CVE-2017-14737 is a medium-severity vulnerability in Debian Debian Linux, published on 26 Sep 2017. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2017-14737 in the wild and no public exploit code.

Affected product: Debian Debian 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.
