* closes bpo-39510: Fix use-after-free in BufferedReader.readinto() (GH-18350)Miss Islington (bot)2020-02-041-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When called on a closed object, readinto() segfaults on account of a write to a freed buffer: ==220553== Process terminating with default action of signal 11 (SIGSEGV): dumping core ==220553== Access not within mapped region at address 0x2A ==220553== at 0x48408A0: memmove (vg_replace_strmem.c:1272) ==220553== by 0x58DB0C: _buffered_readinto_generic (bufferedio.c:972) ==220553== by 0x58DCBA: _io__Buffered_readinto_impl (bufferedio.c:1053) ==220553== by 0x58DCBA: _io__Buffered_readinto (bufferedio.c.h:253) Reproducer: reader = open ("/dev/zero", "rb") _void = reader.read (42) reader.close () reader.readinto (bytearray (42)) GH-GH-GH- BANG! The problem exists since 2012 when commit dc469454ec added code to free the read buffer on close().
