- CVEs with nessus.description==Multiple vulnerabilities have been discovered in clamav, the ClamAV AntiVirus toolkit for Unix. Effects range from denial of service to potential arbitrary code execution. Additionally, this version fixes a longstanding issue that has recently resurfaced whereby a malformed virus signature database can cause an application crash and denial of service.
CVE-2017-12374
ClamAV has a use-after-free condition arising from a lack of input validation. A remote attacker could exploit this vulnerability with a crafted email message to cause a denial of service.
CVE-2017-12375
ClamAV has a buffer overflow vulnerability arising from a lack of input validation. An unauthenticated remote attacker could send a crafted email message to the affected device, triggering a buffer overflow and potentially a denial of service when the malicious message is scanned.
CVE-2017-12376
ClamAV has a buffer overflow vulnerability arising from improper input validation when handling Portable Document Format (PDF) files. An unauthenticated remote attacker could send a crafted PDF file to the affected device, triggering a buffer overflow and potentially a denial of service or arbitrary code execution when the malicious file is scanned.
CVE-2017-12377
ClamAV has a heap overflow vulnerability arising from improper input validation when handling mew packets. An attacker could exploit this by sending a crafted message to the affected device, triggering a denial of service or possible arbitrary code execution when the malicious file is scanned.
CVE-2017-12378
ClamAV has a buffer overread vulnerability arising from improper input validation when handling tape archive (TAR) files. An unauthenticated remote attacker could send a crafted TAR file to the affected device, triggering a buffer overread and potentially a denial of service when the malicious file is scanned.
CVE-2017-12379
ClamAV has a buffer overflow vulnerability arising from improper input validation in the message parsing function. An unauthenticated remote attacker could send a crafted email message to the affected device, triggering a buffer overflow and potentially a denial of service or arbitrary code execution when the malicious message is scanned.
CVE-2017-12380
ClamAV has a NULL dereference vulnerability arising from improper input validation in the message parsing function. An unauthenticated remote attacker could send a crafted email message to the affected device, triggering a NULL pointer dereference, which may result in a denial of service.
Debian Bug #824196
A malformed virus signature database could cause an application crash and denial of service.
For Debian 7 'Wheezy', these problems have been fixed in version 0.99.2+dfsg-0+deb7u4.
We recommend that you upgrade your clamav packages.
