CVE-2026-0990 (CNNVD-202601-2641)
中文标题:
libxml2 安全漏洞
英文标题:
Libxml2: libxml2: denial of service via uncontrolled recursion in xml catalog processing
漏洞描述
中文描述:
libxml2是GNOME开源的一个用来解析XML文档的函数库。它用C语言写成,并且能为多种语言所调用,例如C语言,C++,XSH。 libxml2存在安全漏洞,该漏洞源于xmlCatalogXMLResolveURI函数在XML目录包含引用自身的委托URI条目时出现不受控制的递归,可能导致远程攻击者通过特制XML目录造成无限递归和调用堆栈耗尽,引发分段违规。
英文描述:
A flaw was found in libxml2, an XML parsing library. This uncontrolled recursion vulnerability occurs in the xmlCatalogXMLResolveURI function when an XML catalog contains a delegate URI entry that references itself. A remote attacker could exploit this configuration-dependent issue by providing a specially crafted XML catalog, leading to infinite recursion and call stack exhaustion. This ultimately results in a segmentation fault, causing a Denial of Service (DoS) by crashing affected applications.
