VUL-0: CVE-2023-50711: aws-nitro-enclaves-cli: vmm-sys-util: out of bounds memory accesses
Last modified: 2024-06-11 13:42:08 UTC
+++ This bug was initially created as a clone of Bug #1218499 +++ vmm-sys-util is a collection of modules that provides helpers and utilities used by multiple rust-vmm components. Starting in version 0.5.0 and prior to version 0.12.0, an issue in the `FamStructWrapper::deserialize` implementation provided by the crate for `vmm_sys_util::fam::FamStructWrapper` can lead to out of bounds memory accesses. The deserialization does not check that the length stored in the header matches the flexible array length. Mismatch in the lengths might allow out of bounds memory access through Rust-safe methods. The issue was corrected in version 0.12.0 by inserting a check that verifies the lengths of compared flexible arrays are equal for any deserialized header and aborting deserialization otherwise. Moreover, the API was changed so that header length can only be modified through Rust-unsafe code. This ensures that users cannot trigger out-of-bounds memory access from Rust-safe code.

SUSE:SLE-15-SP4:Update/aws-nitro-enclaves-cli uses an affected version of the vmm-sys-util crate.
Ok, Olaf, you're the bugowner of that package, as far as I can see, therefore I'm giving this to you. Let me know if you don't think you should be dealing with it and we'll figure things out...

Rudi, do you remember why aws-nitro-enclaves-cli was forked intp SLE15-SP6? The SR lacks details. If possible, remove the forked pkg, and use the pkgs from the existing Update channels.
this was requested by Eugenio on 2024/2/21 to enforce recompilation against openssl-3
I see. In 15.6 the pkg requires "libssl.so.3(OPENSSL_3.0.0)(64bit)", in 15.5 "libssl.so.1.1(OPENSSL_1_1_1)(64bit)". In other words, the fork is required.
update submitted.
