Description Allen Webb 2023-12-04 16:38:37 UTC

From the NVD: https://nvd.nist.gov/vuln/detail/CVE-2023-39976

```
log_blackbox.c in libqb before 2.0.8 allows a buffer overflow via long log messages because the header size is not considered.
```

Reproducible: Always

Looks like this is fixed in 2.0.8: https://github.com/ClusterLabs/libqb/releases/tag/v2.0.8

Comment 2 Allen Webb 2024-01-10 13:44:06 UTC

On ChromeOS we have moved to libqqb 2.0.8 with the same ebuild as 2.0.4 with just a name change and the newer source archive + digests.
