CVE-2016-1583 Privilege escalation in n/a
High 7.8
Published
Updated
Check this codebase for CVE-2016-1583 and fix it if it is affected.
What it is: CVE-2016-1583 is a high-severity vulnerability in Canonical Ubuntu Linux, published on 27 Jun 2016. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2016-1583 exists.
Affected product: Canonical Ubuntu 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.

What is CVE-2016-1583?
CVE-2016-1583 is a high-severity vulnerability in Canonical Ubuntu Linux, published on 27 Jun 2016. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling.
Weakness: CWE-119
