Oracle Linux 7 : curl (ELSA-2023-7743)

medium Nessus Plugin ID 186839

Language:

Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 7 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2023-7743 advisory.

 - 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. (CVE-2022-43552)

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

Solution

Update the affected curl, libcurl and / or libcurl-devel packages.
