Alpine: libcurl, multiple curl packages: security update to 7.74.0-r0

high Tenable Self-Hosted Container Security Plugin ID 423791

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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)

- 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)

- 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)
