CVE-2023-23916

一、漏洞信息
漏洞编号：CVE-2023-23916
漏洞归属组件：curl
漏洞归属的版本：7.71.1,7.77.0,7.78.0,7.79.1,7.86.0
CVSS V3.0分值：
BaseScore：6.5 Medium
Vector：CVSS：3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
漏洞简述：
An allocation of resources without limits or throttling vulnerability exists in curl <v7.88.0 based on the chained HTTP compression algorithms, meaning that a server response can be compressed multiple times and potentially with differentalgorithms. The number of acceptable links in this decompression chain wascapped, but the cap was implemented on a per-header basis allowing a maliciousserver to insert a virtually unlimited number of compression steps simply byusing many headers. The use of such a decompression chain could result in a malloc bomb , making curl end up spending enormous amounts of allocated heap memory, or trying to and returning out of memory errors.
