Debian Security Advisory DSA-5142-1 security@debian.org
https://www.debian.org/security/ Salvatore Bonaccorso
May 22, 2022 https://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : libxml2
CVE ID : CVE-2022-29824
Debian Bug : 1010526
Felix Wilhelm reported that several buffer handling functions in
libxml2, a library providing support to read, modify and write XML and
HTML files, don't check for integer overflows, resulting in
out-of-bounds memory writes if specially crafted, multi-gigabyte XML
files are processed. An attacker can take advantage of this flaw for
denial of service or execution of arbitrary code.
For the oldstable distribution (buster), this problem has been fixed
in version 2.9.4+dfsg1-7+deb10u4.
For the stable distribution (bullseye), this problem has been fixed in
version 2.9.10+dfsg-6.7+deb11u2.
We recommend that you upgrade your libxml2 packages.
For the detailed security status of libxml2 please refer to its security
tracker page at:
