TITLE

libxml2 Code problem vulnerability

DESCRIPTION

An issue was discovered in libxml2 before 2.10.3. Certain invalid XML entity definitions can corrupt a hash table key, potentially leading to subsequent logic errors. In one case, a double-free can be provoked. It is written in C language and can be called by many languages, such as C language, C++, XSH. Currently there is no information about this vulnerability, please keep an eye on CNNVD or vendor announcements.

CVE-2022-40303 Maddie Stone discovered that missing safety checks in several functions can result in integer overflows when parsing a XML document with the XML_PARSE_HUGE option enabled. CVE-2022-40304 Ned Williamson and Nathan Wachholz discovered a vulnerability when handling detection of entity reference cycles, which may result in corrupted dictionary entries. This flaw may lead to logic errors, including memory errors like double free flaws. For the stable distribution (bullseye), these problems have been fixed in version 2.9.10+dfsg-6.7+deb11u3.
