How do you trigger this? I tried both files with "cabextract -t", clamdscan, clamscan and chmd_md5. None of those segfaulted, I saw however the message from clamscan --debug: |Scanning /home/bigeasy/crash449.chm |LibClamAV debug: in cli_magic_scandesc (reclevel: 0/16) |LibClamAV debug: Recognized MS CHM file |LibClamAV debug: cache_check: 18e5f920cca46633a9d21539c00603d2 is negative |LibClamAV debug: mspack_fmap_message() WARNING; PMGL quickref area is too large |LibClamAV debug: mspack_fmap_message() WARNING; contents are corrupt |LibClamAV debug: CDBNAME:CL_TYPE_MSCHM:0:/#IDXHDR:0:4096:0:0:0:(nil) |LibClamAV debug: cli_scanmschm() failed to extract 8 |LibClamAV debug: hashtab: Freeing hashset, elements: 0, capacity: 0 |LibClamAV debug: cli_magic_scandesc: returning 8 at line 2327 |/home/bigeasy/crash449.chm: Can't open file or directory ERROR which seems that it noticed the invalid structure and aborted. I had however no problem reproduce the previous bug. I tried amd64 stable + unstable. Any hints?
