Base vector

AV:N/AC:L/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions PCRE versions prior to 8.38

Description The issue is related to the pcre exec function in pcre exec.c, which mishandles a // pattern with a 01 string. This can be exploited by remote attackers to cause a denial of service, specifically a heap-based buffer overflow, or possibly have other unspecified impacts. The issue can be triggered via a crafted regular expression.

Recommendations For versions prior to 8.38, update to version 8.38 or later to resolve the issue. As a temporary workaround, consider restricting the use of crafted regular expressions to minimize the risk of exploitation.
