Alpine: curl: security update to 7.87.0-r2
critical Tenable Self-Hosted Container Security Plugin ID 404034
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause
HSTS functionality fail when multiple URLs are requested serially. Using its HSTS support, curl can be
instructed to use HTTPS instead of usingan insecure clear-text HTTP step even when HTTP is provided in the
URL. ThisHSTS mechanism would however surprisingly be ignored by subsequent transferswhen done on the same
command line because the state would not be properlycarried on. (CVE-2023-23914)
- A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause
HSTS functionality to behave incorrectly when multiple URLs are requested in parallel. Using its HSTS
support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when
HTTP is provided in the URL. This HSTS mechanism would however surprisingly fail when multiple transfers
are done in parallel as the HSTS cache file gets overwritten by the most recentlycompleted transfer. A
later HTTP-only transfer to the earlier host name would then *not* get upgraded properly to HSTS.
(CVE-2023-23915)
- An allocation of resources without limits or throttling vulnerability exists in curl <v7.88.0 based on the
"chained" HTTP compression algorithms, meaning that a server response can be compressed multiple times and
potentially with differentalgorithms. The number of acceptable "links" in this "decompression chain"
wascapped, but the cap was implemented on a per-header basis allowing a maliciousserver to insert a
virtually unlimited number of compression steps simply byusing many headers. The use of such a
decompression chain could result in a "malloc bomb", making curl end up spending enormous amounts of
allocated heap memory, or trying to and returning out of memory errors. (CVE-2023-23916)
