According to its version, the clamd antivirus daemon on the remote host is earlier than 0.96.1. Such versions are reportedly affected by multiple vulnerabilities :
An error exists within the ‘cli_pdf()’ function in ‘libclamav/pdf.c’ when processing certain PDF files.
(Bug 2016)
An error exists within the ‘parseicon()’ function in ‘libclamav/pe_icons.c’ when processing PE icons. This can be exploited to trigger an out-of-bounds access when reading data and potentially cause a crash via a specially crafted PE file. (Bug 2031)
