CVE-2024-33601
Description
A flaw was found in the glibc netgroup cache. The netgroup cache uses xmalloc/xrealloc and may terminate the process due to a memory allocation failure.
Statement
The flaw in the glibc netgroup cache, while concerning, is categorized as a low severity issue due to several factors. Firstly, the exploitation of this vulnerability requires specific conditions, such as a memory allocation failure within the netgroup cache, which may not occur frequently in typical usage scenarios. Additionally, the impact of such failures is limited to the termination of the affected process, rather than facilitating unauthorized access or data manipulation. Furthermore, the likelihood of successful exploitation and the potential for widespread harm are comparatively low, given the specific nature of the vulnerability and its constrained impact.
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).
