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.

Recommendations For PCRE version 8.40, consider updating to a newer version that addresses this issue. As a temporary workaround, restrict the use of the pcre32 copy substring function in pcre get.c to minimize the risk of exploitation.
