CVE-2021-45423 is fixed in pev on 1 platform by DEBIAN-CVE-2021-45423 (version 0.81-9), released March 13, 2023. It is not reported as exploited. Patch Radar priority: Urgent.
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.
