Some vulnerabilities have been reported in MySQL, which can be exploited by malicious users to cause a DoS (Denial of Service), or potentially by malicious people to execute arbitrary code.

1) MySQL uses a vulnerable version of the zlib library.

For more information:
SA15949

2) A boundary error within the "init_syms()" function when processing "function_name" fields can be exploited by malicious users to cause a stack-based buffer overflow.

Successful exploitation allows execution of arbitrary code, but requires permissions to create user-defined functions.

3) It is possible for malicious users to crash the server and slaves in various ways. See the vendor advisory for details.
