Perl Unicode regular expressions buffer overflow
| perl-unicode-bo (38270) |  High Risk |
Description:
The Perl regular expression engine is vulnerable to a buffer overflow, caused by improper handling of Unicode encoded data. By passing specially-crafted Unicode data to a regular expression using unspecified attack vectors, a remote attacker could overflow a buffer and execute arbitrary code on the system with the privileges of the Perl application.
