Name of the Vulnerable Software and Affected Versions PCRE version 8.40

Description The issue is related to a stack-based buffer overflow in the pcre32 copy substring function. This can be exploited by remote attackers using a crafted file, potentially leading to a denial of service or other unspecified impacts.
