EulerOS 2.0 SP8 : fribidi (EulerOS-SA-2020-1149)

high Nessus Plugin ID 133983

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the fribidi packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

- 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected fribidi package.
