## May 20, 2024
[glibc](packages/glibc.md) `2.34-100.el9_4.security.0.8` contains all of our changes so far rebased on top of 9.4's `2.34-100`,
which was still missing the iconv and nscd security fixes, so our addition of those is still relevant.
[openssh](packages/openssh.md) rebased on 9.4's `8.7p1-38`.
The status page on [CVE-2024-1086](issues/CVE-2024-1086.md) has been updated to refer to EL9 fix.
## April 30, 2024
Unreleased [glibc](packages/glibc.md) `2.34-83.12.el9_3.security.0.6` includes nscd CVE-2024-33599, CVE-2024-33600, CVE-2024-33601, CVE-2024-33602 fixes from upstream glibc 2.34 branch.
This update ended up unreleased because we refocused on 9.4.
## April 18-23, 2024
Our hardened EL9 [glibc](packages/glibc.md) updated to include glibc upstream fix for [CVE-2024-2961](issues/CVE-2024-2961.md).

#### Known-effective vulnerability mitigations and fixes
`2.34-83.12.el9_3.security.0.6` includes nscd CVE-2024-33599, CVE-2024-33600, CVE-2024-33601, CVE-2024-33602 fixes from upstream glibc 2.34 branch.
`2.34-83.12.el9_3.security.0.5` includes `iconv(3)` ISO-2022-CN-EXT [CVE-2024-2961](../issues/CVE-2024-2961.md) fix from upstream glibc 2.34 branch.
`2.34-60.el9_2.security.0.2` included mitigations sufficient to avoid security exposure of [CVE-2023-4911](../issues/CVE-2023-4911.md) 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. In the update to `2.34-60.7.el9_2.security.0.3` and beyond, we retained the mitigations while rebasing on upstream EL's package with upstream fixes for these vulnerabilities (and more).
