CVE-2024-47619 | tranport: TLS host name wildcard matching too lax

Exp

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.

7.5 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:N)
Service keeps running; no real outage angle.
