| Vetor | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
libxml2 versions prior to 2.10.4
Description
The issue is related to the
xmlSchemaFixupComplexType function in the xmlschemas.c file of the libxml2 library, which is associated with a null pointer dereference. This can be exploited by a remote attacker to cause a denial of service. The vulnerability occurs when parsing certain invalid XSD schemas, leading to a NULL pointer dereference and subsequently a segfault.Recommendations
For libxml2 versions prior to 2.10.4, update to version 2.10.4 or later to resolve the issue. As a temporary workaround, consider restricting the parsing of XSD schemas to minimize the risk of exploitation.
