Alpine: multiple pev packages: security update to 0.82-r0

critical Tenable Self-Hosted Container Security Plugin ID 408016

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A Buffer Overflow vulnerabilityexists in Pev 0.81 via the pe_exports function from exports.c.. The array
 offsets_to_Names is dynamically allocated on the stack using exp->NumberOfFunctions as its size. However,
 the loop uses exp->NumberOfNames to iterate over it and set its components value. Therefore, the loop code
 assumes that exp->NumberOfFunctions is greater than ordinal at each iteration. This can lead to arbitrary
 code execution. (CVE-2021-45423)
