  • As-yet unspecified double-free issues involving an error path exist in 'libclamav/vba_extract.c' and 'shared/cdiff.c'. (Bug 2486 and report from <mt*debian.org>)

  • 'libclamav/pdf.c' may miss detection. (Bug 2455)

  • Multiple as-yet unspecified error path leaks exit in 'clamav-milter/whitelist.c', 'clamscan/manager.c', and 'libclamav/sis.c'. (Report from <mt*debian.org>)
