EulerOS 2.0 SP5 : libXfont (EulerOS-SA-2019-2539)

high Nessus Plugin ID 131813

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the libXfont package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- In the PatternMatch function in fontfile/fontdir.c in libXfont through 1.5.2 and 2.x before 2.0.2, an attacker with access to an X connection can cause a buffer over-read during pattern matching of fonts, leading to information disclosure or a crash (denial of service). This occurs because '\0' characters are incorrectly skipped in situations involving ? characters.(CVE-2017-13720)

- In the pcfGetProperties function in bitmap/pcfread.c in libXfont through 1.5.2 and 2.x before 2.0.2, a missing boundary check (for PCF files) could be used by local attackers authenticated to an Xserver for a buffer over-read, for information disclosure or a crash of the X server.(CVE-2017-13722)

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 libXfont packages.
