Описание
An issue was discovered in Perl 5.18 through 5.26. A crafted regular expression can cause a heap-based buffer overflow, with control over the bytes written.
A heap buffer write overflow, with control over the bytes written, was found in the way regular expressions employing Unicode rules are compiled. An attacker, with the ability to provide a specially crafted regular expression, could crash the perl interpreter, or possibly execute arbitrary code.
Отчет
Versions of the perl interpreter older than 5.18 are not vulnerable. As a result, the versions of perl as shipped in Red Hat Enterprise Linux version 7, 6 and 5 are not affected by this vulnerability.
