Package : libxml2
CVE ID : CVE-2023-28484 CVE-2023-29469
Debian Bug : 1034436 1034437
Several vulnerabilities were discovered in libxml2, a library providing
support to read, modify and write XML and HTML files.
CVE-2023-28484
A NULL pointer dereference flaw when parsing invalid XML schemas may
result in denial of service.
CVE-2023-29469
It was reported that when hashing empty strings which aren't
null-terminated, xmlDictComputeFastKey could produce inconsistent
results, which may lead to various logic or memory errors.
For the stable distribution (bullseye), these problems have been fixed in
version 2.9.10+dfsg-6.7+deb11u4.
We recommend that you upgrade your libxml2 packages.
For the detailed security status of libxml2 please refer to its security
tracker page at:
