Description

It was discovered that ClamAV did not properly reallocate memory when processing certain PDF files. A remote attacker could send a specially crafted PDF and crash ClamAV. (CVE-2010-1639)

An out of bounds memory access flaw was discovered in ClamAV. A remote attacker could send a specially crafted Portable Executable (PE) file and crash ClamAV. This issue only affected Ubuntu 10.04 LTS. (CVE-2010-2077).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
