Описание
libxml2 before 2.12.10 and 2.13.x before 2.13.6 has a stack-based buffer overflow in xmlSnprintfElements in valid.c. To exploit this, DTD validation must occur for an untrusted document or untrusted DTD. NOTE: this is similar to CVE-2017-9047.
A flaw was found in libxml2. This vulnerability allows a stack-based buffer overflow via DTD validation of an untrusted document or untrusted DTD.
Отчет
This vulnerability is rated as important because it involves a stack-based buffer overflow in the xmlSnprintfElements function within valid.c. Exploiting this issue requires DTD validation to occur on an untrusted document or untrusted DTD, making it a potential security risk for applications using libxml2 that do not adequately restrict DTD input.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
