Description:
Some vulnerabilities have been reported in Firebird, which can be exploited by malicious users to cause a DoS (Denial of Service) and malicious people to compromise a vulnerable system.
1 ) A vulnerability is caused due to an error within the handling of "connect" requests (0x1) with a large "p_cnct_count" value. This can be exploited to cause a buffer overflow by sending a specially crafted connect request to a vulnerable server (default port 3050/TCP).
2) The "filter_transliterate_text()" function in filters.cpp does not handle certain blob segments correctly. This can lead to an integer truncation which causes the "copy_blob()" in blb.cpp to handle a segment of size 0, resulting in an infinite loop.
The vulnerabilities are reported in Firebird 2. Other versions may also be affected.
