Описание
Heap-based buffer overflow in the pack function in Perl before 5.26.2 allows context-dependent attackers to execute arbitrary code via a large item count.
It was found that the pack() function in the 32-bit version of the perl interpreter was vulnerable to heap buffer overflow via the packing template. An attacker, able to provide a specially crafted template, could use this flaw to crash the interpreter.
Отчет
The 64-bit versions of perl have not been found to be affected. As a result, this issue did not affect the versions of perl as shipped with Red Hat Enterprise Linux 7, and the versions of rh-perl526-perl, rh-perl524-perl and rh-perl520-perl as shipped with Red Hat Software Collections. This issue affects the 32bit versions of perl as shipped with Red Hat Enterprise Linux 6. Red Hat Enterprise Linux 6 is now in Maintenance Support 2 Phase of the support and maintenance life cycle. This has been rated as having a security impact of Low, and is not currently planned to be addressed in future updates. For additional information, refer to the Red Hat Enterprise Linux Life Cycle: https://access.redhat.com/support/policy/updates/errata/.
