Vulnerability Details
CVEID:CVE-2023-38546
**DESCRIPTION:**cURL libcurl could allow a remote attacker to bypass security restrictions, caused by a flaw in the curl_easy_duphandle function if a transfer has cookies enabled when the handle is duplicated. By sending a specially crafted request, an attacker could exploit this vulnerability to insert cookies at will into a running program.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268046 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVEID:CVE-2023-38545
**DESCRIPTION:**libcurl and cURL are vulnerable to a heap-based buffer overflow, caused by the improper handling of hostnames longer than 255 bytes during a slow SOCKS5 proxy handshake. By sending an overly long argument, a remote attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base score: 8.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268045 for the current score.
