Vulnerability identifier: #VU48482

CSH Severity: Medium

CVSS v4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2020-25713

CWE-ID: CWE-125

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the raptor_xml_writer_start_element_common() function in raptor_xml_writer.c. A remote attacker can create a specially crafted PDF file, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
