Categoría:	Mageia Linux Local Security Checks
Título:	Mageia: Security Advisory (MGASA-2021-0371)
Resumen:	The remote host is missing an update for the 'python-pip' package(s) announced via the MGASA-2021-0371 advisory.
Descripción:	Summary: The remote host is missing an update for the 'python-pip' package(s) announced via the MGASA-2021-0371 advisory. Vulnerability Insight: A flaw was found in python-pip in the way it handled Unicode separators in git references. A remote attacker could possibly use this issue to install a different revision on a repository (CVE-2021-3572). The bundled python-urllib3 was also vulnerable to: The urllib3 library 1.26.x before 1.26.4 for Python omits SSL certificate validation in some cases involving HTTPS to HTTPS proxies. The initial connection to the HTTPS proxy (if an SSLContext isn't given via proxy_config) doesn't verify the hostname of the certificate. This means certificates for different servers that still validate properly with the default urllib3 SSLContext will be silently accepted (CVE-2021-28363). An issue was discovered in urllib3 before 1.26.5. When provided with a URL containing many @ characters in the authority component, the authority regular expression exhibits catastrophic backtracking, causing a denial of service if a URL were passed as a parameter or redirected to via an HTTP redirect (CVE-2021-33503). Affected Software/OS: 'python-pip' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 6.4 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:P/A:N
