mageia
May 12, 2022
In libxml2 before 2.9.14, several buffer handling functions in buf.c (xmlBuf*) and tree.c (xmlBuffer*) don't check for integer overflows
Summary
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.
(CVE-2022-29824)
