3) 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.
Upgrade curl to version 7.85.0-6.fc37.
