> Debian Oldstable LibreOffice Important Buffer Overflow Vuln DSA-6251-1

Dun Anh Nguyen discovered a buffer overflow in LibreOffice, which could result in an out-of-bounds write if OOXML documents with malformed encryption parameters are opened. For the oldstable distribution (bookworm), this problem has been fixed in version 4:7.4.7-1+deb12u11.
