Description:
A vulnerability and a security issue have been reported in Amavis, which can be exploited by malicious people to cause a DoS (Denial of Service) or potentially to compromise a vulnerable system.
1) An integer underflow error in the "file" utility can be exploited to cause a heap-based buffer overflow.
For more information:
SA24548
2) The problem is caused due to certain regular expressions in "file", which can consume all available CPU resources when identifying a specially crafted file.
