Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2010-1623

Medium
5.3/10

Summary

Memory Leak in the "apr_brigade_split_line" function in "buckets/apr_brigade.c" in the Apache Portable Runtime Utility library (aka APR-util) versions 0.9x prior to 0.9.18 and 1.x.x prior to 1.3.10, as used in the "mod_reqtimeout" module in the Apache HTTP Server and other software, allows remote attackers to cause a Denial of Service (Memory Consumption) via unspecified vectors related to the destruction of an APR bucket. This issue affects Apache HTTP Server versions 2.0.35 through 2.0.63, 2.2.x prior to 2.2.17, and 2.3.x prior to 2.3.9.

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.
