		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">cURL is a computer software project providing a library (libcurl) and command-line tool (curl) for transferring data using various protocols.\r\n\r\n
Security Fix(es):\r\n\r\n
Due to use of a dangling pointer, libcurl 7.29.0 through 7.71.1 can use the wrong connection when sending data.(CVE-2020-8231)\r\n\r\n
curl 7.41.0 through 7.73.0 is vulnerable to an improper check for certificate revocation due to insufficient verification of the OCSP response.(CVE-2020-8286)\r\n\r\n
curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing.(CVE-2020-8285)\r\n\r\n
A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions.(CVE-2020-8284)\r\n\r\n</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for curl is now available for openEuler-20.03-LTS and openEuler-20.03-LTS-SP1.\r\n\r\n
openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
