Hi, The following vulnerability was published for clamav. CVE-2025-20260[0]: | A vulnerability in the PDF scanning processes of ClamAV could allow | an unauthenticated, remote attacker to cause a buffer overflow | condition, cause a denial of service (DoS) condition, or execute | arbitrary code on an affected device. This vulnerability exists | because memory buffers are allocated incorrectly when PDF files are | processed. An attacker could exploit this vulnerability by | submitting a crafted PDF file to be scanned by ClamAV on an affected | device. A successful exploit could allow the attacker to trigger a | buffer overflow, likely resulting in the termination of the ClamAV | scanning process and a DoS condition on the affected software. | Although unproven, there is also a possibility that an attacker | could leverage the buffer overflow to execute arbitrary code with | the privileges of the ClamAV process. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
