Affected: CleanStart: curl
Multiple security vulnerabilities affect the curl package. These issues are resolved in later releases. See references for individual vulnerability details.
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.

The code that performs password matching when using 'basic' HTTP authentication does not use a constant-time memcmp and has no rate-limiting. An unauthenticated network attacker could brute-force the HTTP basic password byte-by-byte, by recording the webserver's response time until the unauthorized (401) response. CVE-2021-43298 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). The HTTP digest authentication in the GoAhead web server before 5.1.2 does not completely protect against replay attacks. An unauthenticated remote attacker could bypass authentication via capture-replay if TLS is not used to protect the underlying communication channel. CVE-2020-15688 has been assigned to this vulnerability. A CVSS v3 base score of 8.8 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). An issue was discovered in Embedthis GoAhead 2.5.0. Certain pages (ex: goform/login and config/log_off_page.htm) create links containing a hostname obtained from an arbitrary HTTP host header sent by an attacker. This could potentially be used in a phishing attack. CVE-2019-16645 has been assigned to this vulnerability. A CVSS v3 base score of 8.6 has been assigned; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:N). In http.c in Embedthis GoAhead before 4.1.1 and 5.x before 5.0.1, a header parsing vulnerability causes a memory assertion, out-of-bounds mem…

cURL is a computer software project providing a library (libcurl) and command-line tool (curl) for transferring data using various protocols.
