[Clamav-users] Instability and Modern Anti-Virus Software

2008-01-02 Thread Paul Kosinski
There is an article on eWeek.com today concerning instability in AV software due to the impossibility of adequately testing updates when releasing them as quickly as they are needed (www.eweek.com/article2/0,1895,2240656,00.asp?kc=EWKNLINF010208STR3). As I understand it, ClamAV is perhaps unusual

ClamAV's strong point for me, has always been the ability to turn off just about anything causing an issue. I haven't seen this kind of fine detail ability in any AV product (commercial or free) that can match ClamAV for flexibility. In theory, anything can mess up an AV package. ClamAV had a

Hello everyone, 1) ClamAV uses own functions to create temporary files. One such routine is vulnerable to a race condition attack. The analysis is incorrect. The author mistakenly assumed that name_salt is fixed and this is not true. After each call to cli_gentemp() name_salt gets updated
