## What is CVE-2019-18932?

CVE-2019-18932 is a high-severity vulnerability in Opensuse Backports Sle, published on 21 Jan 2020. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

log.c in Squid Analysis Report Generator (sarg) through 2.3.11 allows local privilege escalation. By default, it uses a fixed temporary directory /tmp/sarg. As the root user, sarg creates this directory or reuses an existing one in an insecure manner. An attacker can pre-create the directory, and place symlinks in it (after winning a /tmp/sarg/denied.int_unsort race condition). The outcome will be corrupted or newly created files in privileged file system locations.

Weakness: CWE-59 (Improper Link Resolution Before File Access), CWE-362 (Concurrent Execution using Shared Resource with Improper Synchronization)

```text
Check this codebase for CVE-2019-18932 and fix it if it is affected.

What it is: CVE-2019-18932 is a high-severity vulnerability in Opensuse Backports Sle, published on 21 Jan 2020. 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-2019-18932 in the wild and no public exploit code.

Affected product: Opensuse Backports Sle. 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.
