Date: April 14, 2009
Updated: April 17, 2009
Bug(s): #232665, #253497

Synopsis

Description

The following vulnerabilities were found:
  • Multiple errors when processing UPX, ASPack or Microsoft Office files (CVE-2008-3243).
  • Infinite Sergio Alvarez of n.runs AG reported an invalid memory access when processing a CHM file with a large nb_dir value (CVE-2008-3244).
  • Jonathan Brossard from iViZ Techno Solutions reported that F-PROT Antivirus does not correctly process ELF binaries with corrupted headers (CVE-2008-5747).
