Multiple vulnerabilities in ClamAV could allow a remote attacker to cause a denial of service (DoS) condition, interrupting scanning operations.For more information about these vulnerabilities, see the Details section of this advisory.For additional information on these vulnerabilities in ClamAV, see the ClamAV blog. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities. Notes:The Security Impact Rating (SIR) for these vulnerabilities is High for Windows-based platforms only because those platforms run the ClamAV scanning process in a privileged security context. The platforms that are highly impacted include Cisco Secure Endpoint Connector for Windows.The SIR for these vulnerabilities is Medium on other platforms, including Linux and Mac platforms, because those platforms run the ClamAV scanning process in a lower-privileged security context. The affected platforms include Secure Endpoint Connector for Linux and Mac.Cisco Secure Endpoint Private Cloud itself is not impacted by these vulnerabilities. However, the Cisco Secure Endpoint Connector software that is distributed from the device is impacted.This advisory is available at the following link:https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-clamav-88cFYyxR
A vulnerability in the HTML Cascading Style Sheets (CSS) module of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper error handling when splitting UTF-8 strings. An attacker could exploit this vulnerability by submitting a crafted HTML file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to terminate the scanning process.

A vulnerability in the Object Linking and Embedding 2 (OLE2) decryption routine of ClamAV could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to an integer underflow in a bounds check that allows for a heap buffer overflow read. An attacker could exploit this vulnerability by submitting a crafted file containing OLE2 content to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to terminate the ClamAV scanning process, resulting in a DoS condition on the affected software. For a description of this vulnerability, see the . Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
A vulnerability in the dynamic link library (DLL) loading mechanism in Cisco Advanced Malware Protection (AMP) for Endpoints Windows Connector, ClamAV for Windows, and Immunet could allow an authenticated, local attacker to perform a DLL hijacking attack on an affected Windows system. To exploit this vulnerability, the attacker would need valid credentials on the system. The vulnerability is due to insufficient validation of directory search paths at run time. An attacker could exploit this vulnerability by placing a malicious DLL file on an affected system. A successful exploit could allow the attacker to execute arbitrary code with SYSTEM privileges.
Unspecified vulnerability in libclamav/phishcheck.c in ClamAV before 0.90.3 and 0.91 before 0.91rc1, when running on Solaris, allows remote attackers to cause a denial of service (hang) via unknown vectors related to the isURL function and regular expressions.
Gibraltar Firewall 2.2 and earlier, when using the ClamAV update to 0.81 for Squid, uses a defunct ClamAV method to scan memory for viruses, which does not return an error code and prevents viruses from being detected.

Stack consumption vulnerability in libclamav/special.c in ClamAV before 0.94.2 allows remote attackers to cause a denial of service (daemon crash) via a crafted JPEG file, related to the clicheckjpegexploit, jpegcheckphotoshop, and jpegcheckphotoshop8bim functions.
Off-by-one error in the getunicodename function (libclamav/vbaextract.c) in Clam Anti-Virus (ClamAV) before 0.94.1 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted VBA project file, which triggers a heap-based buffer overflow.
libclamav/petite.c in ClamAV before 0.93.3 allows remote attackers to cause a denial of service via a malformed Petite file that triggers an out-of-bounds memory access. NOTE: this issue exists because of an incomplete fix for CVE-2008-2713.
libclamav/petite.c in ClamAV before 0.93.1 allows remote attackers to cause a denial of service via a crafted Petite file that triggers an out-of-bounds read.
ClamAV before 0.93 allows remote attackers to bypass the scanning enging via a RAR file with an invalid version number, which cannot be parsed by ClamAV but can be extracted by Winrar.
libclamunrar in ClamAV before 0.93 allows remote attackers to cause a denial of service (crash) via crafted RAR files that trigger "memory problems," as demonstrated by the PROTOS GENOME test suite for Archive Formats.
Heap-based buffer overflow in pe.c in libclamav in ClamAV 0.92.1 allows remote attackers to execute arbitrary code via a crafted WWPack compressed PE binary.
The rfc2231 function in message.c in libclamav in ClamAV before 0.93 allows remote attackers to cause a denial of service (crash) via a crafted message that produces a string that is not null terminated, which triggers a buffer over-read.
libclamav/chmunpack.c in the chm-parser in ClamAV before 0.94 allows remote attackers to cause a denial of service (application crash) via a malformed CHM file, related to an "invalid memory access."
ClamAV before 0.93 allows remote attackers to cause a denial of service (CPU consumption) via a crafted ARJ archive, as demonstrated by the PROTOS GENOME test suite for Archive Formats.
Buffer overflow in the cliscanpe function in libclamav (libclamav/pe.c) for ClamAV 0.92 and 0.92.1 allows remote attackers to execute arbitrary code via a crafted Upack PE file.
Heap-based buffer overflow in spin.c in libclamav in ClamAV 0.92.1 allows remote attackers to execute arbitrary code via a crafted PeSpin packed PE binary with a modified length value.
Integer overflow in the cliscanpe function in libclamav in ClamAV before 0.92.1, as used in clamd, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted Petite packed PE file, which triggers a heap-based buffer overflow.
