Test case differences from upstream: + +- The test module needs to explicitly link against libnss_files on + RHEL-8; upstream libnss_files is built into libc.so. + +- Test module code was adapted to not use the upstream NSS module + convenience macros. + +This change is adapted from the following commit from upstream: + +commit 973fe93a5675c42798b2161c6f29c01b0e243994 +Author: Siddhesh Poyarekar +Date: Fri Sep 15 13:51:12 2023 -0400 + + getaddrinfo: Fix use after free in getcanonname (CVE-2023-4806) + + When an NSS plugin only implements the _gethostbyname2_r and + _getcanonname_r callbacks, getaddrinfo could use memory that was freed + during tmpbuf resizing, through h_name in a previous query response. + + The backing store for res->at->name when doing a query with + gethostbyname3_r or gethostbyname2_r is tmpbuf, which is reallocated in + gethosts during the query. For AF_INET6 lookup with AI_ALL | + AI_V4MAPPED, gethosts gets called twice, once for a v6 lookup and second + for a v4 lookup. In this case, if the first call reallocates tmpbuf + enough number of times, resulting in a malloc, th->h_name (that + res->at->name refers to) ends up on a heap allocated storage in tmpbuf. + Now if the second call to gethosts also causes the plugin callback to + return NSS_STATUS_TRYAGAIN, tmpbuf will get freed, resulting in a UAF + reference in res->at->name. This then gets dereferenced in the + getcanonname_r plugin call, resulting in the use after free. + + Fix this by copying h_name over and freeing it at the end. This + resolves BZ #30843, which is assigned CVE-2023-4806. + + Signed-off-by: Siddhesh Poyarekar + +diff --git a/nss/Makefile b/nss/Makefile +index cfb255c6e7a3a4de..5829a2539306ddb5 100644 +--- a/nss/Makefile ++++ b/nss/Makefile +@@ -66,7 +66,8 @@ xtests = bug-erange + tests-container = \ + tst-nss-db-endpwent \ + tst-nss-db-endgrent \ +- tst-nss-gai-actions ++ tst-nss-gai-actions \ ++ tst-nss-gai-hv2-canonname + + # Tests which need libdl + ifeq (yes,$(build-shared)) +@@ -132,7 +133,8 @@ routines += $(libnss_files-routines) + static-only-routines += $(libnss_files-routines) + tests-static += tst-nss-static + endif +-extra-test-objs += nss_test1.os nss_test2.os nss_test_errno.os ++extra-test-objs += nss_test1.os nss_test2.os nss_test_errno.os \ ++ nss_test_gai_hv2_canonname.os + + include ../Rules + +@@ -169,12 +171,17 @@ rtld-tests-LDFLAGS += -Wl,--dynamic-list=nss_test.ver + libof-nss_test1 = extramodules + libof-nss_test2 = extramodules + libof-nss_test_errno = extramodules ++libof-nss_test_gai_hv2_canonname = extramodules + $(objpfx)/libnss_test1.so: $(objpfx)nss_test1.os $(link-libc-deps) + $(build-module) + $(objpfx)/libnss_test2.so: $(objpfx)nss_test2.os $(link-libc-deps) + $(build-module) + $(objpfx)/libnss_test_errno.so: $(objpfx)nss_test_errno.os $(link-libc-deps) + $(build-module) ++$(objpfx)/libnss_test_gai_hv2_canonname.so: \ ++ $(objpfx)nss_test_gai_hv2_canonname.os $(link-libc-deps) \ ++ $(objpfx)/libnss_files.so ++ $(build-module) + $(objpfx)nss_test2.os : nss_test1.c + ifdef libnss_test1.so-version + $(objpfx)/libnss_test1.so$(libnss_test1.so-version): $(objpfx)/libnss_test1.so +@@ -187,10 +194,14 @@ endif + $(objpfx)/libnss_test_errno.so$(libnss_files.so-version): \ + $(objpfx)/libnss_test_errno.so + $(make-link) ++$(objpfx)/libnss_test_gai_hv2_canonname.so$(libnss_files.so-version): \ ++ $(objpfx)/libnss_test_gai_hv2_canonname.so ++ $(make-link) + $(patsubst %,$(objpfx)%.out,$(tests)) : \ + $(objpfx)/libnss_test1.so$(libnss_test1.so-version) \ + $(objpfx)/libnss_test2.so$(libnss_test2.so-version) \ +- $(objpfx)/libnss_test_errno.so$(libnss_files.so-version) ++ $(objpfx)/libnss_test_errno.so$(libnss_files.so-version) \ ++ $(objpfx)/libnss_test_gai_hv2_canonname.so$(libnss_files.so-version) + + ifeq (yes,$(have-thread-library)) + $(objpfx)tst-cancel-getpwuid_r: $(shared-thread-library) +diff --git a/nss/nss_test_gai_hv2_canonname.c b/nss/nss_test_gai_hv2_canonname.c +new file mode 100644 +index 0000000000000000..4195d7d24fdd5f6d +--- /dev/null ++++ b/nss/nss_test_gai_hv2_canonname.c +@@ -0,0 +1,64 @@ ++/* NSS service provider that only provides gethostbyname2_r. ++ Copyright The GNU Toolchain Authors. ++ This file is part of the GNU C Library. ++ ++ The GNU C Library is free software; you can redistribute it and/or ++ modify it under the terms of the GNU Lesser General Public ++ License as published by the Free Software Foundation; either ++ version 2.1 of the License, or (at your option) any later version. ++ ++ The GNU C Library is distributed in the hope that it will be useful, ++ but WITHOUT ANY WARRANTY; without even the implied warranty of ++ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
