Summary
Red Hat Security Advisory: git-lfs security and bug fix update

Notes

Topic
An update for git-lfs is now available for Red Hat Enterprise Linux 8. 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
Git Large File Storage (LFS) replaces large files such as audio samples, videos, datasets, and graphics with text pointers inside Git, while storing the file contents on a remote server. Security Fix(es): * golang: net/http/httputil: ReverseProxy should not forward unparseable query parameters (CVE-2022-2880) * golang: regexp/syntax: limit memory used by parsing regexps (CVE-2022-41715) * golang: net/http: excessive memory growth in a Go server accepting HTTP/2 requests (CVE-2022-41717) 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. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.8 Release Notes linked from the References section.
