Vulnerability Details

CVEID:   CVE-2022-32205
DESCRIPTION:   cURL libcurl is vulnerable to a denial of service, caused by an issue with the ability to set excessive amounts of Set-Cookie: headers in a HTTP response to curl by a server. By persuading a victim to connect a specially-crafted server, a remote attacker could exploit this vulnerability to create requests that become larger than the threshold, and results in a denial of service condition.
CVSS Base score: 4.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/229739 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)

CVEID:   CVE-2022-32206
DESCRIPTION:   cURL libcurl is vulnerable to a denial of service, caused by a flaw in the number of acceptable "links" in the "chained" HTTP compression algorithms. By persuading a victim to connect a specially-crafted server, a remote attacker could exploit this vulnerability to insert a virtually unlimited number of compression steps, and results in a denial of service condition.
CVSS Base score: 4.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/229740 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)

CVEID:   CVE-2022-32207
DESCRIPTION:   cURL libcurl could allow a remote attacker to obtain sensitive information, caused by improper preservation of permissions when saving cookies, alt-svc and hsts data to local files. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/229741 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)

CVEID:   CVE-2022-32208
DESCRIPTION:   cURL libcurl is vulnerable to a man-in-the-middle attack, caused by a flaw in the handling of message verification failures. An attacker could exploit this vulnerability to launch a man-in-the-middle attack and gain access to the communication channel between endpoints to inject data to the client..
CVSS Base score: 3.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/229742 for the current score.
