ALSA-2023:2478 — Low: curl security update

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: Incorrect handling of control code characters in cookies (CVE-2022-35252) * curl: Use-after-free triggered by an HTTP proxy deny response (CVE-2022-43552)

fkie_cve-2022-43552

A use after free vulnerability exists in curl <7.87.0. Curl can be asked to *tunnel* virtually all protocols it supports through an HTTP proxy. HTTP proxies can (and often do) deny such tunnel operations. When getting denied to tunnel the specific protocols SMB or TELNET, curl would use a heap-allocated struct after it had been freed, in its transfer shutdown code path.

ICSA-23-131-05 — Siemens SINEC NMS Third-Party

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 was used 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 subsequent `POST` request. The problem exists in the logic for a reused handle when it is changed from a PUT to a POST. When curl is used to retrieve and parse cookies from a HTTP(S) server, itaccepts cookies using control codes that when later are sent back to a HTTPserver might make the server return 400 responses. Effectively allowing a"sister site" to deny service to all siblings. curl can be told to parse a `.netrc` file for credentials. If that file endsin a line with 4095 consecutive non-white space letters and no newline, curlwould first read past the end of the stack-based buffer, and if the readworks, write a zero byte beyond its boundary.This will in most cases cause a segfault or similar, but circumstances might also cause different outcomes.If a malicious user can provide a custom netrc file to an application or otherwise affect its contents, this flaw could be used as denial-of-service. libexpat before 2.4.9 has a use-after-free in the doContent function in xmlparse.c. curl before 7.86.0 has a double free. If curl is told to use an HTTP proxy for a tra…

OESA-2023-1005 — curl security update

Affected: openEuler:20.03-LTS-SP1: curl

cURL is a computer software project providing a library (libcurl) and command-line tool (curl) for transferring data using various protocols. Security Fix(es): A vulnerability was found in curl. In this issue, curl can be asked to tunnel all protocols virtually it supports through an HTTP proxy. HTTP proxies can deny these tunnel operations using an appropriate HTTP error response code. When getting denied to tunnel the specific SMB or TELNET protocols, curl can use a heap-allocated struct after it has been freed and shut down the code path in its transfer.(CVE-2022-43552)
