Описание
A stack buffer overflow was found in Internationl components for unicode (ICU ). While running the genrb binary, the 'subtag' struct overflowed at the SRBRoot::addTag function. This issue may lead to memory corruption and local arbitrary code execution.
Отчет
Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low. Red Hat follows best practice and federal requirements for least privilege, allowing only specific processes to be run with isolated accounts specific to team and federal platforms that have limited privileges that are only used for a single task. The environment leverages file integrity checks and malicious code protections, such as IPS/IDS and antimalware solutions, to help detect and prevent malicious code that attempts to exploit buffer overflow vulnerabilities. Robust input validation and error-handling mechanisms ensure all user inputs are thoroughly validated, preventing improperly validated inputs from causing system instability, exposing sensitive data, or escalating risks.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
