Versions mentioned in the description apply to the upstream
Remediation section below for
Alpine:3.10 relevant versions.
A heap use-after-free flaw was found in curl versions from 7.59.0 through 7.61.1 in the code related to closing an easy handle. When closing and cleaning up an 'easy' handle in the
Curl_close() function, the library code first frees a struct (without nulling the pointer) and might then subsequently erroneously write to a struct field within that already freed struct.
curl to version 7.62.0-r0 or higher.
