Amazon Linux 2 : fribidi (ALAS-2020-1434)

high Nessus Plugin ID 137091

Language:

Synopsis

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

Description

A buffer overflow in the fribidi_get_par_embedding_levels_ex() function in lib/fribidi-bidi.c of GNU FriBidi through 1.0.7 allows an attacker to cause a denial of service or possibly execute arbitrary code by delivering crafted text content to a user, when this content is then rendered by an application that uses FriBidi for text layout calculations. Examples include any GNOME or GTK+ based application that uses Pango for text layout, as this internally uses FriBidi for bidirectional text layout. For example, the attacker can construct a crafted text file to be opened in GEdit, or a crafted IRC message to be viewed in HexChat. (CVE-2019-18397)

Solution

Run 'yum update fribidi' to update your system.
