Description Marco Benatto 2025-04-07 18:21:27 UTC 
Hello,

we have received a heads-up about a security flaw in llama-cpp upstream, the security flaw is a RCE in llama-cpp RPC mechanism which were reported on:

https://retr0.blog/blog/llama-rpc-rce

Looking at the project's GitHub security advisory page at:
https://github.com/ggml-org/llama.cpp/security

I see there's no advisory nor CVE reported for this, however there's a upstream commit mentioning the RCE and containing a fix:

https://github.com/ggml-org/llama.cpp/commit/1d20e53c40c3cc848ba2b95f5bf7c075eeec8b19

The commit above was included firstly on b4657 tag:

$ git tag --contains 1d20e53c40c3cc848ba2b95f5bf7c075eeec8b19 | head -10

b4658
b4659
b4660
b4661
b4662
b4663
b4666
b4667
b4671

Looking at latest llama-cpp build on Koji it seems it's on b4580 tag:

https://koji.fedoraproject.org/koji/buildinfo?buildID=2675105

built on last March 9th which doesn't currently have the commit.

Reproducible: Always
