Upgrade Alpine:3.20 curl to version 8.9.1-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Alpine.
See How to fix? for Alpine:3.20 relevant fixed versions and status.
libcurl's ASN1 parser code has the GTime2str() function, used for parsing an
ASN.1 Generalized Time field. If given an syntactically incorrect field, the
parser might end up using -1 for the length of the time fraction, leading to
a strlen() getting performed on a pointer to a heap buffer area that is not
(purposely) null terminated.
This flaw most likely leads to a crash, but can also lead to heap contents getting returned to the application when CURLINFO_CERTINFO is used.
