Inefficient Regular Expression Complexity Affecting nscd package, versions *
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

CVE-2009-5155 (opens in a new tab)How to fix?
There is no fixed version for RHEL:6 nscd.
NVD Description
Note: Versions mentioned in the description apply only to the upstream nscd package and not the nscd package as distributed by RHEL.
See How to fix? for RHEL:6 relevant fixed versions and status.
In the GNU C Library (aka glibc or libc6) before 2.28, parse_reg_exp in posix/regcomp.c misparses alternatives, which allows attackers to cause a denial of service (assertion failure and application exit) or trigger an incorrect result by attempting a regular-expression match.
