Improper Verification of Cryptographic Signature vulnerability in LibreOffice allows PDF Signature Spoofing by Improper Validation.
In the affected versions of LibreOffice a flaw in the verification code for adbe.pkcs7.sha1 signatures could cause invalid signatures to be accepted as valid
This issue affects LibreOffice: from 24.8 before < 24.8.6, from 25.2 before < 25.2.2.
LibreOffice supports Office URI Schemes to enable browser integration of LibreOffice with MS SharePoint server. An additional scheme 'vnd.libreoffice.command' specific to LibreOffice was added. In the affected versions of LibreOffice a link in a browser using that scheme could be constructed with an embedded inner URL that when passed to LibreOffice could call internal macros with arbitrary arguments. This issue affects LibreOffice: from 24.8 before < 24.8.5, from 25.2 before < 25.2.1.

Improper Validation of Array Index vulnerability in the spreadsheet component of The Document Foundation LibreOffice allows an attacker to craft a spreadsheet document that will cause an array index underflow when loaded. In the affected versions of LibreOffice certain malformed spreadsheet formulas, such as AGGREGATE, could be created with less parameters passed to the formula interpreter than it expected, leading to an array index underflow, in which case there is a risk that arbitrary code could be executed. This issue affects: The Document Foundation LibreOffice 7.4 versions prior to 7.4.6; 7.5 versions prior to 7.5.1.

Improper access control in editor components of The Document Foundation LibreOffice allowed an attacker to craft a document that would cause external links to be loaded without prompt. In the affected versions of LibreOffice documents that used "floating frames" linked to external files, would load the contents of those frames without prompting the user for permission to do so. This was inconsistent with the treatment of other linked content in LibreOffice. This issue affects: The Document Foundation LibreOffice 7.4 versions prior to 7.4.7; 7.5 versions prior to 7.5.3.

The Portable Document Format (PDF) specification does not provide any information regarding the concrete procedure of how to validate signatures. Consequently, an Incremental Saving vulnerability exists in multiple products. When an attacker uses the Incremental Saving feature to add pages or annotations, Body Updates are displayed to the user without any action by the signature-validation logic. This affects Foxit Reader before 9.4 and PhantomPDF before 8.3.9 and 9.x before 9.4. It also affects LibreOffice, Master PDF Editor, Nitro Pro, Nitro Reader, Nuance Power PDF Standard, PDF Editor 6 Pro, PDFelement6 Pro, PDF Studio Viewer 2018, PDF Studio Pro, Perfect PDF 10 Premium, and Perfect PDF Reader.
libreoffice-7.0.2.2+ Impress aborts with a stack smashing error when provided a crafted .odp presentation file, on GNOME with the "scale" Display setting set to 175%. The issue is likely due to a problem in the cairo dependency. This could be related to [1] and is likely caused by [2]

LibreOffice and OpenOffice automatically open embedded content
The getapppath function in desktop/unx/source/start.c in LibreOffice through 6.0.5 mishandles the realpath function in certain environments such as FreeBSD libc, which might allow attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact if LibreOffice is automatically launched during web browsing with pathnames controlled by a remote web site.
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.

LibreOffice before 2017-03-17 has an out-of-bounds write caused by a heap-based buffer overflow related to the ReadJPEG function in vcl/source/filter/jpeg/jpegc.cxx.
Use-after-free vulnerability in LibreOffice before 5.1.4 allows remote attackers to execute arbitrary code via a crafted RTF file, related to stylesheet and superscript tokens.
LibreOffice before 5.0.5 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted LwpTocSuperLayout record in a LotusWordPro (lwp) document.
The lwp filter in LibreOffice before 5.0.4 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted LotusWordPro (lwp) document.
Integer overflow in LibreOffice before 4.4.5 and Apache OpenOffice before 4.1.2 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a long DOC file, which triggers a buffer overflow.
LibreOffice before 4.4.5 and Apache OpenOffice before 4.1.2 uses the stored LinkUpdateMode configuration information in OpenDocument Format files and templates when handling links, which might allow remote attackers to obtain sensitive information via a crafted document, which embeds data from local files into (1) Calc or (2) Writer.
Integer underflow in LibreOffice before 4.4.5 and Apache OpenOffice before 4.1.2, when the configuration setting "Load printer settings with the document" is enabled, allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via crafted PrinterSetup data in an ODF document.
LibreOffice before 4.4.6 and 5.x before 5.0.1 and Apache OpenOffice before 4.1.2 allows remote attackers to cause a denial of service (memory corruption and application crash) or execute arbitrary code via an index to a non-existent bookmark in a DOC file.
LibreOffice before 4.3.5 allows remote attackers to cause a denial of service (invalid write operation and crash) and possibly execute arbitrary code via a crafted RTF file.
