EulerOS 2.0 SP9 : curl (EulerOS-SA-2023-1838)

high Nessus Plugin ID 175519

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 :

- 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. (CVE-2023-23916)

- A vulnerability in input validation exists in curl <8.0 during communication using the TELNET protocol may allow an attacker to pass on maliciously crafted user name and 'telnet options' during server negotiation.
The lack of proper input scrubbing allows an attacker to send content or perform option negotiation without the application's intent. This vulnerability could be exploited if an application allows user input, thereby enabling attackers to execute arbitrary code on the system. (CVE-2023-27533)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected curl packages.
