Affected: AlmaLinux:9: curl, AlmaLinux:9: curl-minimal, AlmaLinux:9: libcurl, AlmaLinux:9: libcurl-devel, AlmaLinux:9: libcurl-minimal
The curl packages provide the libcurl library and the curl utility for downloading files from servers using various protocols, including HTTP, FTP, and LDAP. Security Fix(es): * curl: HTTP compression denial of service (CVE-2022-32206) * curl: Unpreserved file permissions (CVE-2022-32207) * curl: FTP-KRB bad message verification (CVE-2022-32208) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Affected: CleanStart: curl
Multiple security vulnerabilities affect the curl package. These issues are resolved in later releases. See references for individual vulnerability details.
curl < 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms. The number of acceptable "links" in this "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps.The use of such a decompression chain could result in a "malloc bomb", makingcurl end up spending enormous amounts of allocated heap memory, or trying toand returning out of memory errors.

zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches. A use-after-free in Busybox 1.35-x's awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the copyvar function. A malicious server can serve excessive amounts of "Set-Cookie:" headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on "foo.example.com" can set cookies that also would match for "bar.example.com", making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method. curl < 7.84.0 supports "chained" HTTP compression algorithms, meaning that a serverresponse can be compressed multiple times and potentially with different algorithms.

Security Fix(es): A vulnerability was found in curl. This issue occurs because it mishandles message verification failures when curl does FTP transfers secured by krb5. This flaw makes it possible for a Man-in-the-middle attack to go unnoticed and allows data injection into the client.(CVE-2022-32208) A vulnerability was found in curl. This issue occurs because the number of acceptable "links" in the "decompression chain" was unbounded, allowing a malicious server to insert a virtually unlimited number of compression steps. This flaw leads to a denial of service, either by mistake or by a malicious actor.(CVE-2022-32206) A vulnerability was found in curl. This issue occurs because when curl saves cookies, alt-svc, and HSTS data to local files, it makes the operation atomic by finalizing the process with a rename from a temporary name to the final target file name. This flaw leads to unpreserved file permissions, either by mistake or by a malicious actor.(CVE-2022-32207) A vulnerability was found in curl. This issue occurs because a malicious server can serve excessive amounts of `Set-Cookie:` headers in an HTTP response to curl, which stores all of them. This flaw leads to a denial of service, either by mistake or by a malicious actor.(CVE-2022-32205)

UPDATE A: Two devices (ENERGY AXC PU, SMARTRTU AXC SG) added (24.11.2022) Update for PLCnext Firmware containing fixes for recent vulnerability findings in Linux components and security enhancements. PLCnext Control AXC F x152 is certified according to IEC 62443-4-1 and IEC 62443-4-2. This certification requires that all third-party components used in the firmware are regularly checked for known vulnerabilities.
Ein Angreifer kann mehrere Schwachstellen in cURL ausnutzen, um einen Denial of Service Angriff durchzuführen, Sicherheitseinstellungen zu umgehen und Daten offenzulegen oder zu manipulieren.
