Описание
A flaw was found in the libssh library in versions less than 0.11.2. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, which is used in further processing. This vulnerability allows an authenticated remote attacker to potentially read unintended memory regions, exposing sensitive information or affect service behavior.
Отчет
This issue requires an attacker with valid credentials to access a server, limiting the scope to legitimate users of the SFTP service. Due to this reason, this flaw has been rated with a Moderate severity. Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-125: Out-of-bounds Read vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low. The use of baseline configurations, change control, and configuration settings within the platform enforces secure system configurations, patch management, and proper runtime settings, which helps prevent the introduction of memory handling issues through insecure defaults, unpatched components, and misconfigurations. Specifically, the use of process isolation and memory protection ensures memory integrity by isolating processes and enforcing memory protection mechanisms that limit an attacker's ability to exploit or read memory. System monitoring controls provide an additional layer of protection in the detection of anomalous behavior and unauthorized memory-related access.
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.
