The cygwin clamav packages (Clam AntiVirus - GPL anti-virus toolkit) has
been updated to 0.90.3-1.
Several vulnerabilities were discovered in ClamAV by various
* Victor Stinner (INL) discovered that the OLE2 parser may enter in
an infinite loop (CVE-2007-2650).
* A boundary error was also reported by an anonymous researcher in
the file unsp.c, which might lead to a buffer overflow
* The file unrar.c contains a heap-based buffer overflow via a
modified vm_codesize value from a RAR file (CVE-2007-3123).
* The RAR parsing engine can be bypassed via a RAR file with a header
flag value of 10 (CVE-2007-3122).
* The cli_gentempstream() function from clamdscan creates temporary
files with insecure permissions (CVE-2007-3024).
A remote attacker could send a specially crafted file to the scanner,
possibly triggering one of the vulnerabilities. The two buffer
overflows are reported to only cause Denial of Service. This would lead
to a Denial of Service by CPU consumption or a crash of the scanner.
The insecure temporary file creation vulnerability could be used by a
local user to access sensitive data.
All ClamAV users should upgrade to the latest version 0.90.3-1
[ 1 ] CVE-2007-2650
[ 2 ] CVE-2007-3023

Clam AntiVirus is an anti-virus toolkit for Unix. The main purpose of
this software is the integration with mail servers (attachment
scanning). The package provides a flexible and scalable multi-threaded
daemon, a commandline scanner, and a tool for automatic updating via
Internet. The programs are based on a shared library distributed with
the Clam AntiVirus package, which you can use in your own software.
The clamav package comes in three parts:
clamav: the executables and binaries
libclamav2: the shared library since 0.90.1
libclamav-devel: development resources (headers, static- and import
Cygwin Package Changes:
fixed BUILD_CLAMD in cygwin configure logic (again)
re-applied broken DIRENT_MISSING_D_INO patch
