A vulnerability has been found in unixODBC 2.0.10/2.3.0/2.3.1 (Operating System) and classified as problematic. This vulnerability affects the function SQLDriverConnect
. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect availability. CVE summarizes:
** DISPUTED ** Buffer overflow in the SQLDriverConnect function in unixODBC 2.0.10, 2.3.1, and earlier allows local users to cause a denial of service (crash) via a long string in the FILEDSN option. NOTE: this issue might not be a vulnerability, since the ability to set this option typically implies that the attacker already has legitimate access to cause a DoS or execute code, and therefore the issue would not cross privilege boundaries. There may be limited attack scenarios if isql command-line options are exposed to an attacker, although it seems likely that other, more serious issues would also be exposed, and this issue might not cross privilege boundaries in that context.
The weakness was published 08/31/2012 (Website). The advisory is shared for download at openwall.com. This vulnerability was named CVE-2012-2657 since 05/14/2012. The exploitation appears to be easy.
