Amazon Linux 2 : freetype (ALAS-2023-1909)

critical Nessus Plugin ID 170438

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of freetype installed on the remote host is prior to 2.8-14. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1909 advisory.

A heap buffer overflow flaw was found in Freetype's sfnt_init_face() function in the sfobjs.c file. The vulnerability occurs when creating a face with a strange file and invalid index. This flaw allows an attacker to read and modify a small amount of memory, causing the application to crash. (CVE-2022-27404)

A segmentation fault was found in the FreeType library. This flaw allows an attacker to attempt access to a memory location in a way that could cause an application to halt or crash, leading to a denial of service. (CVE-2022-27405)

A segmentation fault was found in FreeType's FT_Request_Size() function in the ftobjs.c file. This flaw allows an attacker to access a memory location in a way that could cause an application to halt or crash, leading to a denial of service. (CVE-2022-27406)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update freetype' to update your system.
