Overview
Affected versions of this package are vulnerable to Race Condition in the process of counting and allocating memory for ELF core dump program headers, due to a race condition between counting dumpable VM map entries and populating program headers. An attacker can cause an out-of-bounds write on the kernel heap by mutating the VM map between the two passes, potentially leading to privilege escalation. This is only exploitable if an unprivileged local user shares an address space with a process that dumps core.
