Perl is vulnerable to remote code execution vulnerability. The vulnerability exists in the function S_regatom of the file regcomp.c of the component Regex Handler. An integer-overflow and a heap-based buffer-overflow vulnerability occur because it fails to properly bounds-check user-supplied input before copying it to an insufficiently sized memory buffer. Attackers could exploit these issues to execute arbitrary code on the affected application and failed attempts will likely cause a denial service of condition.
