CVE-2024-33602
Description
A flaw was found in the glibc netgroup cache. The buffer-resizing code in addgetnetgrentX assumes that all string pointers point into the supplied buffer. This can potentially lead to memory corruption and cause a crash.
Statement
The identified flaw in the glibc netgroup cache, while significant in its potential to cause memory corruption and crashes, may be categorized as a low severity issue due to several factors. Firstly, the exploitation of this vulnerability requires specific conditions to be met, such as the presence of netgroup-related functionality and the ability to manipulate memory within the target system. Secondly, the impact of the vulnerability is limited to the context of the affected application or system component, rather than posing a system-wide or network-wide threat.
This issue affects the nscd RPM package and not the glibc RPM package itself. Affected components are tracked by their RPM source package, in this case, the nscd binary package is built from the glibc source package, hence the affected component is glibc.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
