This security issue was discovered by Secunia. It currently affects ALL versions of Clam AV. (0.92.1 is the lastest). The new release should be out soon.

Rating: Highly critical
Impact: System access
Where: From remote

The vulnerability is caused due to a boundary error within the
"cli_scanpe()" function in libclamav/pe.c. This can be exploited to
cause a heap-based buffer overflow via a specially crafted "Upack"
executable.

It seems that the vulnerable part is in the code for PE files (windows portable executables) While the possible impact to pure Linux user is unclear, you might want to switch off the ScanPE option in clam.conf before it gets fixed.

!8!
