ClamAV < 0.97.8 Multiple Vulnerabilities

Versions of ClamAV earlier than 0.97.8 are potentially affected by the following vulnerabilities :

• An overflow condition in ‘libclamav/pdf.c’ may be triggered as user-supplied input is not properly validated when handling a specially crafted encrypted PDF file. This may allow a context-dependent attacker to cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code. (CVE-2013-2021)

• An overflow condition in ‘libclamav/pe.c’ may be triggered as user-supplied input is not properly validated when handling a specially crafted UPX-packed executable file. This may allow a context-dependent attacker to cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code. (CVE-2013-2020)
