Vulnerability Details

CVEID:CVE-2021-28861
**DESCRIPTION:**Python could allow a remote attacker to conduct phishing attacks, caused by
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/234228 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N)

CVEID:CVE-2022-45061
**DESCRIPTION:**Python is vulnerable to a denial of service, caused by an unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder. By sending a specially-crafted input, a remote attacker could exploit this vulnerability to cause a CPU denial of service condition.
CVSS Base score: 7.5

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2020-10735
**DESCRIPTION:**Python is vulnerable to a denial of service, caused by the failure to limit amount of digits converting text to int by the int() type in PyLong_FromString(). A remote attacker could exploit this vulnerability to consume all available resources.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/235840 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-40897
**DESCRIPTION:**Pypa Setuptools is vulnerable to a denial of service, caused by improper input validation. By sending request with a specially crafted regular expression, an remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/243028 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2022-40303
**DESCRIPTION:**Gnome libxml2 could allow a remote attacker to execute arbitrary code on the system, caused by an integer overflow in the XML_PARSE_HUGE function. By persuading a victim to open a specially-crafted file, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/238602 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID:CVE-2022-40304
**DESCRIPTION:**Gnome ibxml2 could allow a remote attacker to execute arbitrary code on the system, caused by a dict corruption flaw. By persuading a victim to open a specially-crafted file, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/238603 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

CVEID:CVE-2016-3709
**DESCRIPTION:**GNOME libxml2 is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the KippoInput.class.php script. A remote attacker could exploit this vulnerability using the $file_link parameter to inject malicious script into a Web page which would be executed in a victim’s Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim’s cookie-based authentication credentials.
CVSS Base score: 7.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/232446 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N)

CVEID:CVE-2015-20107
**DESCRIPTION:**Python could allow a remote attacker to execute arbitrary commands on the system, caused by improper input validation in mailcap module. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary commands on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/224937 for the current score.
