libcurl 7.32.0 < 8.9.1 DoS (CVE-2024-7264)

medium Nessus Plugin ID 205024

Language:

Synopsis

The remote host contains a version of libcurl that is affected by a DoS vulnerability.

Description

The version of libcurl installed on the remote host is between 7.32.0 and prior to 8.9.1. It is, therefore, affected by a denial of service (DoS) vulnerability. libcurl's ASN1 parser code has the GTime2str() function, used for parsing an ASN.1 Generalized Time field. If given an syntactically incorrect field, the parser might end up using -1 for the length of the time fraction, leading to a strlen() getting performed on a pointer to a heap buffer area that is not (purposely) null terminated. This flaw most likely leads to a crash, but can also lead to heap contents getting returned to the application when CURLINFO_CERTINFO is used.

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

Solution

Upgrade Curl to version 8.9.1 or later
