The Windows binary GSV48W32.EXE of "gsview" ships with a zlib32.dll (originally named zlib.dll) v1.2.2 which is vulnerable to CAN-2005-2096. The zlib32.dll is dated 2005-03-06 (GSview 4.8 was release 2005-03-26), i.e. before CAN-2005-2096 was published, so its very likely that all the binaries provided by the author will show a vulnerable zlib if they contain one. A scan with ClamAV against the patterns published by Florian Weimer at verifies the presence of the patterns of the vulnerable code: | x:\>clamscan --database CAN-2005-2096.db | ZLIB32.DLL: CAN-2005-2096.zlib-1.2.2 FOUND | | ----------- SCAN SUMMARY ----------- | Known viruses: 16 | Engine version: 0.91.2 | Scanned directories: 1 | Scanned files: 1 Stefan Kanthak
