curl vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 23.04
  • Ubuntu 22.10
  • Ubuntu 22.04 LTS
  • Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in curl.

Software Description:

  • curl: HTTP, HTTPS, and FTP client and client libraries

Details:

Hiroki Kurosawa discovered that curl incorrectly handled validating certain
certificate wildcards. A remote attacker could possibly use this issue to
spoof certain website certificates using IDN hosts. (CVE-2023-28321)

Hiroki Kurosawa discovered that curl incorrectly handled callbacks when
certain options are set by applications. This could cause applications
using curl to misbehave, resulting in information disclosure, or a denial
of service. (CVE-2023-28322)

It was discovered that curl incorrectly handled saving cookies to files. A
local attacker could possibly use this issue to create or overwrite files.
This issue only affected Ubuntu 22.10, and Ubuntu 23.04. (CVE-2023-32001)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

CVE-2023-32001

libcurl can be told to save cookie, HSTS and/or alt-svc data to files. When doing this, it called `stat()` followed by `fopen()` in a way that made it vulnerable to a TOCTOU race condition problem. By exploiting this flaw, an attacker could trick the victim to create or overwrite protected files holding this data in ways it was not intended to.

Ubuntu Security Notice USN-6237-2

Ubuntu Security Notice 6237-2 - USN-6237-1 fixed vulnerabilities in curl. The update caused a certificate wildcard handling regression on Ubuntu 22.04 LTS. This update fixes the problem. Hiroki Kurosawa discovered that curl incorrectly handled validating certain certificate wildcards. A remote attacker could possibly use this issue to spoof certain website certificates using IDN hosts. Hiroki Kurosawa discovered that curl incorrectly handled callbacks when certain options are set by applications. This could cause applications using curl to misbehave, resulting in information disclosure, or a denial of service. It was discovered that curl incorrectly handled saving cookies to files. A local attacker could possibly use this issue to create or overwrite files. This issue only affected Ubuntu 22.10, and Ubuntu 23.04.

CVE-2023-28321

An improper certificate validation vulnerability exists in curl <v8.1.0 in the way it supports matching of wildcard patterns when listed as "Subject Alternative Name" in TLS server certificates. curl can be built to use its own name matching function for TLS rather than one provided by a TLS library. This private wildcard matching function would match IDN (International Domain Name) hosts incorrectly and could as a result accept patterns that otherwise should mismatch. IDN hostnames are converted to puny code before used for certificate checks. Puny coded names always start with `xn--` and should not be allowed to pattern match, but the wildcard check in curl could still check for `x*`, which would match even though the IDN name most likely contained nothing even resembling an `x`.

CVE-2023-28322

An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously wasused to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the second transfer. The problem exists in the logic for a reused handle when it is (expected to be) changed from a PUT to a POST.
