Version: 4.8.1-4
Severity: important

Hi,

The following vulnerability was published for syslog-ng.

CVE-2024-47619[0]:
| syslog-ng is an enhanced log daemo. Prior to version 4.8.2,
| `tls_wildcard_match()` matches on certificates such as `foo.*.bar`
| although that is not allowed. It is also possible to pass partial
| wildcards such as `foo.a*c.bar` which glib matches but should be
| avoided / invalidated. This issue could have an impact on TLS
| connections, such as in man-in-the-middle situations. Version 4.8.2
| contains a fix for the issue.

Note, while advisory say this is fixed in 4.8.2 it looks that
syslong-ng-4.8.2 tag does not contain the fix? I might have missed
something indeed, and asked upstream in [1] about it.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
