2) Memory corruption

EUVDB-ID: #VU11531

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2017-5029

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to write arbitrary files, cause DoS condition or execute arbitrary files on the target system.

The weakness exists in the xsltAddTextString function in transform.c due to lack of a check for integer overflow during a size calculation. A remote attacker can submit a specially crafted HTML page, trigger out-of-bounds write, write arbitrary files, cause the service to crash or execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.
