EulerOS 2.0 SP8 : curl (EulerOS-SA-2024-2022)

low Nessus Plugin ID 202949

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the curl packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

When an application tells libcurl it wants to allow HTTP/2 server push, and the amount of received headers for the push surpasses the maximum allowed limit (1000), libcurl aborts the server push. When aborting, libcurl inadvertently does not free all the previously allocated headers and instead leaks the memory.
Further, this error condition fails silently and is therefore not easily detected by an application.(CVE-2024-2398)

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.(CVE-2023-28322)

Tenable has extracted the preceding description block directly from the EulerOS curl security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected curl packages.
