A vulnerability was found in liblouis, versions 2.5.x before 2.5.4. A stack-based buffer overflow was found in findTable() in liblouis. An attacker could create a malicious file that would cause applications that use liblouis (such as Orca) to crash, or potentially execute arbitrary code when opened.

Security Fix(es) :

  - A missing fix for one stack-based buffer overflow in     findTable() for CVE-2014-8184 was discovered. An     attacker could cause denial of service or potentially     allow arbitrary code execution. (CVE-2017-15101)

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

  - Multiple flaws were found in the processing of     translation tables in liblouis. An attacker could crash     or potentially execute arbitrary code using malicious     translation tables. (CVE-2014-8184, CVE-2017-13738,     CVE-2017-13740, CVE-2017-13741, CVE-2017-13742,     CVE-2017-13743, CVE-2017-13744)

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.

This update for liblouis fixes the following issues: Security issues fixed :

  - CVE-2017-15101: Buffer overflow in findTable     (bsc#1067336).

  - CVE-2014-8184: stack-based buffer overflow in     findTable() (bsc#1062458).

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

Raphael Sanchez Prudencio discovered that Liblouis incorrectly handled certain files. If a user were tricked into opening a crafted file, an attacker could possibly use this to cause a denial of service or potentially execute arbitrary code.

An update for liblouis is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Liblouis is an open source braille translator and back-translator named in honor of Louis Braille. It features support for computer and literary braille, supports contracted and uncontracted translation for many languages and has support for hyphenation. New languages can easily be added through tables that support a rule or dictionary based approach. Liblouis also supports math braille (Nemeth and Marburg).

Security Fix(es) :

* Multiple flaws were found in the processing of translation tables in liblouis. An attacker could crash or potentially execute arbitrary code using malicious translation tables. (CVE-2014-8184, CVE-2017-13738, CVE-2017-13740, CVE-2017-13741, CVE-2017-13742, CVE-2017-13743, CVE-2017-13744)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:3111 advisory.

  - liblouis: stack-based buffer overflow in findTable() (CVE-2014-8184)

  - liblouis: Illegal address access in the _lou_getALine function (CVE-2017-13738)

  - liblouis: Stack-buffer overflow in the parseChars() function (CVE-2017-13740)

  - liblouis: Use-after-free in the function compileBrailleIndicator() (CVE-2017-13741)

  - liblouis: Stack-buffer overflow in the function includeFile() (CVE-2017-13742)

  - liblouis: Buffer overflow in the function _lou_showString() (CVE-2017-13743)

  - liblouis: Illegal address access in the _lou_getALine() function (CVE-2017-13744)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
