The SwCTBWrapper::Read function in sw/source/filter/ww8/ww8toolbar.cxx in LibreOffice before 5.4.6.1 and 6.x before 6.0.2.1 does not validate a customizations index, which allows 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.

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

  - The SwCTBWrapper::Read function in     sw/source/filter/ww8/ww8toolbar.cxx in LibreOffice     before 5.4.6.1 and 6.x before 6.0.2.1 does not validate     a customizations index, which allows 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.(CVE-2018-10120)

  - An information disclosure vulnerability occurs when     LibreOffice 6.0.3 and Apache OpenOffice Writer 4.1.5     automatically process and initiate an SMB connection     embedded in a malicious file, as demonstrated by     xlink:href=file://192.168.0.2/test.jpg within an     office:document-content element in a .odt XML     document.(CVE-2018-10583)

The LibreOffice installed on the remote host is either 5.x prior to 5.4.6 or 6.x prior to 6.0.2. A heap-based buffer overflow condition exists in The SwCTBWrapper::Read function due to improperly checking the bounds of the index into the dynamically allocated buffer. An unauthenticated, remote attacker can exploit this, via a specifically crafted word document opened by user to cause a denial of service condition or the execution of arbitrary code.

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

The LibreOffice installed on the remote macOS host is either 5.x prior to 5.4.6 or 6.x prior to 6.0.2. A heap-based buffer overflow condition exists in The SwCTBWrapper::Read function due to improperly checking the bounds of the index into the dynamically allocated buffer. An unauthenticated, remote attacker can exploit this, via a specifically crafted word document opened by user to cause a denial of service condition or the execution of arbitrary code.

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.
