Improper Restriction of Operations within the Bounds of a Memory Buffer


Severity High
Score 9/10


Multiple buffer overflows in Oracle 9i Database release 2, Release 1, 8i, 8.1.7, and 8.0.6 allow remote attackers to execute arbitrary code via (1) a long conversion string argument to the TO_TIMESTAMP_TZ function, (2) a long time zone argument to the TZ_OFFSET function, or (3) a long DIRECTORY parameter to the BFILENAME function.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
