Rocky Linux 8 : perl (RLSA-2021:1678)

high Nessus Plugin ID 184937

Synopsis

The remote Rocky Linux host is missing one or more security updates.

Description

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:1678 advisory.

- Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow. (CVE-2020-10543)

- 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. (CVE-2020-10878)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
