CVE-2022-29824 | BDVDB-2026-175229 Detail
SiemensSIMATIC S7-1500 CPU 1518-4 PN/DP MFP
Description#
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.
Impact#
No impact statement in the source data.
Weaknesses#
