Description


NGSSoftware has reported some vulnerabilities in Sybase ASE, which can be exploited by malicious users to compromise a vulnerable system and by malicious people to cause a DoS (Denial of Service).

1) A boundary error within the "attrib_valid" function can be exploited to cause a stack-based buffer overflow.

2) A boundary error within the "convert" function can be exploited to cause a stack-based buffer overflow.

3) A boundary error within the "declare" statement can be exploited to cause a stack-based buffer overflow.

4) A boundary error within the handling of query plans can be exploited to cause a stack-based buffer overflow.

5) A boundary error within the handling of the "install java" statement can be exploited to cause a stack-based buffer overflow.

Successful exploitation requires database owner or "sa" privileges.

6) An unspecified error in the xp_server process can be exploited to crash it by passing invalid data to the service.

The vulnerabilities have been reported in versions 12.5.3 and prior.


Solution:
Update to version 12.5.3 ESD#1.
