Overview

About vulnerability

In libxml2 before 2.9.14, several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*) don’t check for integer overflows. This can result in out-of-bounds memory writes. Exploitation requires a victim to open a crafted, multi-gigabyte XML file. Other software using libxml2’s buffer functions, for example libxslt through 1.1.35, is affected as well.

Details

Affected packages:
libxslt @ 1.1.28 (+10 more)
