 漏洞归属组件：[perl](https://gitee.com/src-openeuler/perl)
 漏洞归属的版本：5.28.3,5.32.0,5.34.0,5.38.0
 CVSS V3.0分值：
  BaseScore：N/A None
  Vector：CVSS：3.0/
 漏洞简述：
  A heap buffer overflow vulnerability was discovered in Perl. Release branches 5.34, 5.36, 5.38 and 5.40 are affected, including development versions from 5.33.1 through 5.41.10.When there are non-ASCII bytes in the left-hand-side of the `tr` operator, `S_do_trans_invmap` can overflow the destination pointer `d`.   $ perl -e  $_ =   x{FF}  x 1000000; tr/ xFF/ x{100}/;     Segmentation fault (core dumped)It is believed that this vulnerability can enable Denial of Service and possibly Code Execution attacks on platforms that lack sufficient defenses.
