CVE-2015-7499

CVSS v2.0

5.0

Média

VetorAV:N/AC:L/Au:N/C:P/I:N/A:N
Name of the Vulnerable Software and Affected Versions libxml2 versions prior to 2.9.3
Description The issue is a heap-based buffer overflow in the xmlGROW function in parser.c in libxml2. This allows context-dependent attackers to obtain sensitive process memory information via unspecified vectors. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to use an excessive amount of CPU, leak potentially sensitive information, or crash the application.
Recommendations For versions prior to 2.9.3, update to version 2.9.3 or later to resolve the issue. As a temporary workaround, consider restricting the use of the xmlGROW function in parser.c to minimize the risk of exploitation. Avoid processing untrusted or specially crafted XML or HTML files with libxml2 until the issue is resolved.
