Package: request-tracker5
Version: 5.0.1+dfsg-1
Severity: serious
Tags: security

Hi,

upstream has fixed the following issue in 5.0.2:

"In previous versions, RT's native login system is vulnerable to user 
enumeration through a timing side-channel attack. This means an external 
entity could try to find valid usernames by attempting logins and 
comparing the time to evaluate each login attempt for valid and invalid 
usernames. This vulnerability does not allow any access to the RT 
system. This vulnerability is assigned CVE-2021-38562 and is fixed
in this release."

It would be nice if you could upgrade (or cherry-pick) that fix, please 
also mention 'CVE-2021-38562' in the changelog when doing so.

Regards,
Daniel
