sot/source/sdstor/stgstrms.cxx in LibreOffice before 5.4.5.1 and 6.x before 6.0.1.1 uses an incorrect integer data type in the StgSmallStrm class, which allows remote attackers to cause a denial of service (use-after-free with write access) or possibly have unspecified other impact via a crafted document that uses the structured storage ole2 wrapper file format.

The version of LibreOffice installed on the remote Windows host is either 5.x prior to 5.4.5 or 6.x prior to 6.0.1. It is, therefore, affected by the following vulnerabilities:

  - An arbitrary file read vulnerability exists in the     COM.MICROSOFT.WEBSERVICE function due to improper     validation of a URL input. An unauthenticated, remote     attacker can exploit this, via a specially crafted file,     to read arbitrary files and disclose sensitive information.
    (CVE-2018-6871)

  - A use after free vulnerability exists in the StgSmallStrm     class due to the use of a short data type. An unauthenticated,     remote attacker can exploit this, via a specially crafted     file that uses the structured storage ole2 wrapper, to     execute arbitrary code. (CVE-2018-10119)

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

The version of LibreOffice installed on the remote macOS host is either 5.x prior to 5.4.5 or 6.x prior to 6.0.1. It is, therefore, affected by the following vulnerabilities:

It was discovered that LibreOffice incorrectly handled certain document files. If a user were tricked into opening a specially crafted document, a remote attacker could cause LibreOffice to crash, and possibly execute arbitrary code. (CVE-2018-10119, CVE-2018-10120, CVE-2018-11790)

It was discovered that LibreOffice incorrectly handled embedded SMB connections in document files. If a user were tricked in to opening a specially crafted document, a remote attacker could possibly exploit this to obtain sensitive information. (CVE-2018-10583)

Alex Infuhr discovered that LibreOffice incorrectly handled embedded scripts in document files. If a user were tricked into opening a specially crafted document, a remote attacker could possibly execute arbitrary code. (CVE-2018-16858).

Security Fix(es) :

  - libreoffice: Use-after-free in     sdstor/stgstrms.cxx:StgSmallStrm class allows for denial     of service with crafted document (CVE-2018-10119)

  - libreoffice: Out of bounds write in     filter/ww8/ww8toolbar.cxx:SwCTBWrapper class allows for     denial of service with crafted document (CVE-2018-10120)

  - libreoffice: Information disclosure via SMB connection     embedded in malicious file (CVE-2018-10583)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:3054 advisory.

  - libreoffice: Use-after-free in sdstor/stgstrms.cxx:StgSmallStrm class allows for denial of service with     crafted document (CVE-2018-10119)

  - libreoffice: Out of bounds write in filter/ww8/ww8toolbar.cxx:SwCTBWrapper class allows for denial of     service with crafted document (CVE-2018-10120)

  - libreoffice: Information disclosure via SMB connection embedded in malicious file (CVE-2018-10583)

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

This update for libreoffice to 6.0.4.2 fixes lots of bugs and also the following issues :

Security issues fixed :

  - CVE-2018-10120: The SwCTBWrapper::Read function in     sw/source/filter/ww8/ww8toolbar.cxx did not validate a     customizations index, which allowed remote attackers to     cause a denial of service (heap-based buffer overflow     with write access) or possibly have unspecified other     impact via a crafted document that contains a certain     Microsoft Word record. (bsc#1089706)

  - CVE-2018-10119: sot/source/sdstor/stgstrms.cxx used an     incorrect integer data type in the StgSmallStrm class,     which allowed remote attackers to cause a denial of     service (use-after-free with write access) or possibly     have unspecified other impact via a crafted document     that uses the structured storage ole2 wrapper file     format. (bsc#1089705)

Other issues fixed :

  - DOCX import: missing table background color

  - Bring back offline help per popular demand as lto saves     space we could use with it bsc#915996

Two vulnerabilities were discovered in LibreOffice's code to parse MS Word and Structured Storage files, which could result in denial of service and potentially the execution of arbitrary code if a malformed file is opened.

Fuzzing by the OSS-Fuzz project found two memory safety issues in LibreOffice, which could result in an application crash or possibly other unspecified impact.

For Debian 7 'Wheezy', these problems have been fixed in version 1:3.5.4+dfsg2-0+deb7u11.

We recommend that you upgrade your libreoffice packages.
