TITLE

cURL  Incorrectly resolved name and reference usage vulnerabilities in

DESCRIPTION

libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse, if one of them matches the setup.Due to errors in the logic, the config matching function did not take 'issuercert' into account and it compared the involved paths *case insensitively*,which could lead to libcurl reusing wrong connections.File paths are, or can be, case sensitive on many systems but not all, and caneven vary depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can setto qualify how to verify the server certificate. cURL There is a vulnerability in the use of incorrectly resolved names and references.Information may be obtained. A security issue has been found in curl before version 7.78.0. The comparison also didn't include the 'issuer cert' which a transfer can set to qualify how to verify the server certificate. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: rh-dotnet31-curl security update Advisory ID: RHSA-2022:1354-01 Product: .NET Core on Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2022:1354 Issue date: 2022-04-13 CVE Names: CVE-2021-22876 CVE-2021-22924 CVE-2021-22946 CVE-2021-22947 ==================================================================== 1.
