RHEL 6 : freetype (Unpatched Vulnerability)

critical Nessus Plugin ID 198605

Synopsis

The remote Red Hat 6 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

 - freetype: Use of uninitialized memory (CVE-2014-9746)

 - FreeType before 2.4.11 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via vectors related to BDF fonts and the improper handling of an allocation error in the bdf_free_font function. (CVE-2012-5668)

 - The parse_encoding function in type1/t1load.c in FreeType before 2.5.3 allows remote attackers to cause a denial of service (infinite loop) via a broken number-with-base in a Postscript stream, as demonstrated by 8#garbage. (CVE-2014-9745)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
