Description


Two vulnerabilities have been reported in ClamAV, which can be exploited by malicious people to cause a DoS (Denial of Service).

1) An error exists within the "cli_pdf()" function in libclamav/pdf.c when processing certain PDF files. This can be exploited to e.g. cause a crash via specially crafted PDF files.

2) 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.

The vulnerabilities are reported in version 0.96. Prior versions may also be affected.

Update to version 0.96.1.
