In unixODBC before 2.3.5, there is a buffer overflow in the unicode_to_ansi_copy() function in DriverManager/__info.c.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - unixODBC: Insecure buffer copy in SQLWriteFileDSN function in odbcinst/SQLWriteFileDSN.c (CVE-2018-7485)

  - 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. (CVE-2011-1145)

  - 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. (CVE-2012-2657)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.
