The SQLWriteFileDSN function in odbcinst/SQLWriteFileDSN.c in unixODBC 2.3.5 has strncpy arguments in the wrong order, which allows attackers to cause a denial of service or possibly have unspecified other impact.
In unixODBC before 2.3.5, there is a buffer overflow in the unicodetoansicopy() function in DriverManager/info.c.
An out-of-bounds stack write flaw was found in unixODBC on 64-bit architectures where the caller has 4 bytes and callee writes 8 bytes. This issue may go unnoticed on little-endian architectures, while big-endian architectures can be broken.
The SQLDriverConnect() function in unixODBC before 2.2.14p2 have a possible buffer overflow condition when specifying a large value for SAVEFILE parameter in the connection string.
DISPUTED Buffer overflow in the SQLDriverConnect function in unixODBC 2.3.1 allows local users to cause a denial of service (crash) via a long string in the DRIVER 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.
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.
