[BZ #13579] Do not free l_initfini and allow it to be reused on subsequent dl_open calls for the same library. This fixes the invalid memory access in do_lookup_x when the previously free'd l_initfini was accessed through l_searchlist when a library had been opened for the second time. (cherry picked from commit 0479b305c5b7c8e3fa8e3002982cf8cac02b842e) ----------------------------------------------------------------------- Summary of changes: ChangeLog | 11 +++++++++++ NEWS | 3 ++- elf/dl-close.c | 15 +++------------ elf/dl-deps.c | 7 ++++--- elf/dl-libc.c | 9 ++++++--- elf/rtld.c | 2 ++ include/link.h | 8 ++++---- 7 files changed, 32 insertions(+), 23 deletions(-) -- You are receiving this mail because: You are on the CC list for the bug.
