Red Hat Security Advisory: curl security update
Notes
Topic
An update for curl is now available for Red Hat Enterprise Linux 8.2 Extended Update Support.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP.
Security Fix(es):
* curl: Content not matching hash in Metalink is not being discarded (CVE-2021-22922)
* curl: Metalink download sends credentials (CVE-2021-22923)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
