An Invalid Memory Address Dereference exists in the function elf_end in libelf in elfutils through v0.174. Although eu-size is intended to support ar files inside ar files, handle_ar in size.c closes the outer ar file before handling all inner entries. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file.

Container scanning and Dependency scanning report leaked to unauthorized users
Hi GitLab Security team
### Summary
GitLab makes the container scanning and dependency scanning information available as part of a JSON endpoint for merge requests. These reports are output of the CI job and should only be displayed if the visiting user has access to CI. However, right now GitLab displays the the container scanning and dependency scanning reports regardless of this permission, making it available to whoever has access to the merge request.
For public projects, GitLab allows to restrict CI pipelines to project members only (public pipelines disabled). However, in this case, the merge request widget still renders the scanning reports result, which is the outcome of a CI pipeline.
