Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Information disclosure
EUVDB-ID: #VU62641
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-27774
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to curl attempts to follow redirects during authentication process and does not consider different port numbers or protocols to be separate authentication targets. If the web application performs redirection to a different port number of protocol, cURL will allow such redirection and will pass credentials. It could also leak the TLS SRP credentials this way.
By default, curl only allows redirects to HTTP(S) and FTP(S), but can be asked to allow redirects to all protocols curl supports.
MitigationUpdate curl package to version 7.74.0-1.3+deb11u7.
Vulnerable software versionsDebian Linux: All versions
curl (Debian package): before 7.74.0-1.3+deb11u7

Q & A
Can this vulnerability be exploited remotely?

2) Allocation of Resources Without Limits or Throttling
EUVDB-ID: #VU72337
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-23916
CWE-ID:
CWE-770 - Allocation of Resources Without Limits or Throttling
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to incorrect implementation of the "chained" HTTP compression algorithms, where the number of links in the decompression chain was limited for each header instead of the entire request. A remote attacker can send a specially crafted compressed HTTP request with numerous headers and perform a denial of service (DoS) attack.
Update curl package to version 7.74.0-1.3+deb11u7.
