nscd: netgroup cache may terminate daemon on memory allocation failure
The Name Service Cache Daemon's (nscd) netgroup cache uses xmalloc or
xrealloc and these functions may terminate the process due to a memory
allocation failure resulting in a denial of service to the clients. The
flaw was introduced in glibc 2.15 when the cache was added to nscd.
This vulnerability is only present in the nscd binary.
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.
Отчет
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.
Меры по смягчению последствий
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.
