CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2021-33035 – Buffer overflow from a crafted DBF file
https://notcve.org/view.php?id=CVE-2021-33035
Apache OpenOffice opens dBase/DBF documents and shows the contents as spreadsheets. DBF are database files with data organized in fields. When reading DBF data the size of certain fields is not checked: the data is just copied into local variables. A carefully crafted document could overflow the allocated space, leading to the execution of arbitrary code by altering the contents of the program stack. This issue affects Apache OpenOffice up to and including version 4.1.10 Apache OpenOffice abre documentos dBase/DBF y muestra el contenido como hojas de cálculo. • http://www.openwall.com/lists/oss-security/2021/10/07/3 https://github.com/apache/openoffice/commit/efddaef0151af3be16078cc4d88c6bae0f911e56#diff-ea66e734dd358922aba12ad4ba39c96bdc6cbde587d07dbc63d04daa0a30e90f https://lists.apache.org/thread.html/r1ab8532e11f41bc7ca057ac7e39cab25f2e1f9d5f4929788ae21c8b9%40%3Cusers.openoffice.apache.org%3E https://lists.apache.org/thread.html/r929c0c6a53cad64a1007b878342756badbb05ddd9b8f31a6d0b424cb%40%3Cannounce.apache.org%3E • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVSS: 8.8EPSS: 1%CPEs: 1EXPL: 0CVE-2021-30245 – Code execution in Apache OpenOffice via non-http(s) schemes in Hyperlinks
https://notcve.org/view.php?id=CVE-2021-30245
The project received a report that all versions of Apache OpenOffice through 4.1.8 can open non-http(s) hyperlinks. The problem has existed since about 2006 and the issue is also in 4.1.9. If the link is specifically crafted this could lead to untrusted code execution. It is always best practice to be careful opening documents from unknown and unverified sources. The mitigation in Apache OpenOffice 4.1.10 (unreleased) assures that a security warning is displayed giving the user the option of continuing to open the hyperlink. • https://lists.apache.org/thread.html/r7c01173f763b0c4212ada0e6ab283984d6e058d72258efce85c006ab%40%3Cannounce.apache.org%3E https://lists.apache.org/thread.html/r87ff11512e4883052991e6b725e20294224034ea8453b811fb3ee735%40%3Cdev.openoffice.apache.org%3E https://lists.apache.org/thread.html/r87ff11512e4883052991e6b725e20294224034ea8453b811fb3ee735%40%3Cusers.openoffice.apache.org%3E https://lists.apache.org/thread.html/ra2cabdc083d5160a84de9a6436296ee5030fb3a16dc490dee4f983d5%40%3Cdev.openoffice.apache.org%3E https://lists.apache.org/thread.html/ra2cabdc083d5160a84de9a6436296ee5030fb3a16dc490dee4f983d5%4 • CWE-610: Externally Controlled Reference to a Resource in Another Sphere •
