NVD Description

Note: Versions mentioned in the description apply only to the upstream uap-core package and not the uap-core package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

uap-core before 0.7.3 is vulnerable to a denial of service attack when processing crafted User-Agent strings. Some regexes are vulnerable to regular expression denial of service (REDoS) due to overlapping capture groups. This allows remote attackers to overload a server by setting the User-Agent header in an HTTP(S) request to maliciously crafted long strings. This has been patched in uap-core 0.7.3.
