CVE-2023-34364 — A buffer overflow was discovered in Progress DataDirect Connect for ODBC before 08.02.2770 for Oracle

Critical CVSS 9.8

A buffer overflow was discovered in Progress DataDirect Connect for ODBC before 08.02.2770 for Oracle. An overly large value for certain options of a connection string may overrun the buffer allocated to process the string value. This allows an attacker to execute code of their choice on an affected host by copying carefully selected data that will be executed as code.

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
