- glibc (adds many security-hardening changes originating from Owl and ALT Linux on top of EL package, fixes [CVE-2023-4527](https://www.openwall.com/lists/oss-security/2023/09/25/1)) - glibc (adds many security-hardening changes originating from Owl and ALT Linux on top of EL package)

The changes are described in more detail in the package changelogs. The changes are described in more detail in the package changelogs.
The inclusion of additional security fixes will be "reverted" if and when those get included in upstream EL packages that we rebase our changes on.
More packages/changes are planned, including override packages also for EL8. More packages/changes are planned, including override packages also for EL8.
#### Known-effective vulnerability mitigations and fixes
`glibc-2.34-60.el9_2.security.0.2` (specifically the `.0.2` version!) includes mitigations sufficient to avoid security exposure of [CVE-2023-4911](https://www.openwall.com/lists/oss-security/2023/10/03/2) and a backport of upstream glibc fix of [CVE-2023-4527](https://www.openwall.com/lists/oss-security/2023/09/25/1) that was not yet in upstream EL.

## Source code ## Source code
Just like for other Rocky Linux SIGs, the source trees for Security SIG packages are maintained in [per-package git repositories](https://git.rockylinux.org/sig/security/src). Each repository contains branches `r8` and/or `r9` corresponding to target EL version.
