17715	udhcp: Avoid leaking uninitialized/stale data udhcp: Avoid leaking uninitialized/stale data I noticed a commit in connman: "gdhcp: Avoid leaking stack data via unitiialized variable" [1] Since gdhcp is just BusyBox udhcp with the serial numbers filed off, I checked if BusyBox udhcp has a related issue. The issue is that the get_option logic assumes any data within the memory area of the buffer is "valid". This reduces the complexity of the function at the cost of reading past the end of the actually received data in the case of specially crafted packets. This is not a problem for the udhcp_recv_kernel_packet data path as the entire memory area is zeroed. However, d4/d6_recv_raw_packet does not zero the memory. Note that a related commit [2] is not required as we are zeroing any data that can be read by the get_option function.

17712	install: Fix chown resetting suid/sgid bits from chmod install: Fix chown resetting suid/sgid bits from chmod Since Linux 2.2.13, chown(2) resets the suid/gid bits for all users. This patch changes the ordering so that chmod gets called after chown. This behavior follows GNU coreutils.

17710	tsort: avoid use-after-free tsort: avoid use-after-free When the input data contained a cycle it was possible for tsort to attempt to access freed nodes.

17709	ash: initialize basepf.buf in ash ash: initialize basepf.buf in ash When I planned to print the command in read_line_input, I found that after the system started, the command printed for the first time was always garbled. After analysis, it is found that in the init() function of ash, the variable basepf.buf is not initialized after applying for memory, resulting in garbled initial data. Then assign it to the global variable g_parsefile->buf in ash.c, and then pass g_parsefile->buf to the parameter command of the function read_line_input in the function preadfd(), and finally cause it to be garbled when the command is printed by read_line_input. The call stack is as follows: #0 read_line_input (st=0xb6fff220, prompt=0xb6ffc910 "\\[\\033[32m\\]\\h \\w\\[\\033[m\\] \\$ ", command=command@entry=0xb6ffc230 "P\325\377\266P\325\377\266", maxsize=maxsize@entry=1024) at libbb/lineedit.c:2461 #1 0x0043ef8c in preadfd () at shell/ash.c:10812 #2 preadbuffer () at shell/ash.c:10914 #3 pgetc () at shell/ash.c:10997 #4 0x00440c20 in pgetc_eatbnl () at shell/ash.c:11039 #5 0x00440cbc in xxreadtoken () at shell/ash.c:13157 #6 0x00440f40 in readtoken () at shell/ash.c:13268 #7 0x00441234 in list (nlflag=nlflag@entry=1) at shell/ash.c:11782 #8 0x004420e8 in parsecmd (interact=<optimized out>) at shell/ash.c:13344 #9 0x00442c34 in cmdloop (top=top@entry=1) at shell/ash.c:13549 #10 0x00444e4c in ash_main (argc=<optimized out>, argv=0x444e4c <ash_main+1328>) at shell/ash.c:14747 #11 0x00407954 in run_applet_no_and_exit (applet_no=9, name=<optimized out>, argv=0xbefffd34) at libbb/appletlib.c:1024 #12 0x00407b68 in run_applet_and_exit (name=0xbefffe56 "ash", argv=0x9) at libbb/appletlib.c:1047 #13 0x00407f88 in main (argc=<optimized out>, argv=0xbefffd34) at libbb/appletlib.c:1181 Fixes: 82dd14a510ca ("ash: use CONFIG_FEATURE_EDITING_MAX_LEN") Signed-off-by: zhuyan <zhuyan34@huawei.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	zhuyan	8 months ago
