high Nessus Plugin ID 151704

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SUSE15 host has packages installed that are affected by a vulnerability as referenced in the openSUSE-SU-2021:1655-1 advisory.

- 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)

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 fribidi, fribidi-devel, libfribidi0 and / or libfribidi0-32bit packages.
