Bug ID: 27008
Summary: ld.so.cache should have endianness markup
Product: glibc
Version: unspecified
Status: NEW
Severity: minor
Priority: P2
Component: dynamic-link
Assignee: unassigned at sourceware dot org
Reporter: fweimer at redhat dot com
Target Milestone: ---
Flags: security-
With qemu-user, it's common that a process of the wrong endianness tries to
parse ld.so.cache. For performance reasons, the consistency checks are somewhat
limited, so crashes can be the result.

Eventually, this information could be used to provide a unified cache for qemu-user and similiar scenarios.
