CVE-2017-12376

CVSS v2.0

9.3

High

VectorAV:N/AC:M/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions: ClamAV AntiVirus software versions 0.99.2 and prior
Description: The issue is caused by improper input validation when handling Portable Document Format (.pdf) files, which could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or potentially execute arbitrary code on an affected device. This can be achieved by sending a crafted .pdf file to an affected device, causing a buffer overflow in the handle pdfname function (in pdf.c) when ClamAV scans the malicious file.
Recommendations: For ClamAV AntiVirus software versions 0.99.2 and prior, update to a version later than 0.99.2 to resolve the issue. As a temporary workaround, consider restricting the handling of .pdf files by ClamAV to minimize the risk of exploitation.
