CVE-2020-10878

TITLE

Red Hat Security Advisory 2021-1678-01

DESCRIPTION

Perl before 5.30.3 has an integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection. An input validation error vulnerability exists in Perl versions prior to 5.30.3. The vulnerability is caused by the program's incorrect handling of the \"PL_regkind[OP(n)] == NOTHING\" case. 8) - aarch64, noarch, ppc64le, s390x, x86_64 3. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.4 Release Notes linked from the References section. Bug fix: * RHACM 2.0.8 images (BZ #1915461) 3.
