* Fix leak in getaddrinfo introduced by the fix for CVE-2023-4806 [BZ #30843]Romain Geissler2023-09-261-3/+1
| | | | | | | | | | | | This patch fixes a very recently added leak in getaddrinfo. This was assigned CVE-2023-5156. Resolves: BZ #30884 Related: BZ #30842 Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org> (cherry picked from commit ec6b95c3303c700eb89eebeda2d7264cc184a796)
* getaddrinfo: Fix use after free in getcanonname (CVE-2023-4806)Siddhesh Poyarekar2023-09-151-8/+17
| | | | | | | | | | | | | | | | | | | | | | | | 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 <siddhesh@sourceware.org> (cherry picked from commit 973fe93a5675c42798b2161c6f29c01b0e243994)

* Simplify allocations and fix merge and continue actions [BZ #28931]Siddhesh Poyarekar2022-03-221-52/+91
| | | | | | | | | | | | | | | | | | | | | Allocations for address tuples is currently a bit confusing because of the pointer chasing through PAT, making it hard to observe the sequence in which allocations have been made. Narrow scope of the pointer chasing through PAT so that it is only used where necessary. This also tightens actions behaviour with the hosts database in getaddrinfo to comply with the manual text. The "continue" action discards previous results and the "merge" action results in an immedate lookup failure. Consequently, chaining of allocations across modules is no longer necessary, thus opening up cleanup opportunities. A test has been added that checks some combinations to ensure that they work correctly.

* nss: fix nss_database_lookup2's alternate handling [BZ #27416]DJ Delorie2021-03-091-3/+1
| | | | | | | | | | | | | | | | | | | | __nss_database_lookup2's extra arguments were left unused in the nsswitch reloading patch set; this broke compat (default config ignored) and shadow files (secondary name ignored) which relies on these fallbacks. This patch adds in the previous behavior by correcting the initialization of the database list to reflect the fallbacks. This means that the nss_database_lookup2 interface no longer needs to be passed the fallback info, so API and callers were adjusted. Since all callers needed to be edited anyway, the calls were changed from __nss_database_lookup2 to the faster __nss_database_get. This was an intended optimization which was deferred during the initial lookup changes to avoid touching so many files. The test case verifies that compat targets work (passwd) and that the default configuration works (group). Tested on x86-64.

* Remove stat wrapper functions, move them to exported symbolsAdhemerval Zanella2020-10-091-1/+1

Both the prototypes of the internal symbol linked by the static wrappers and the inline redirectors are also removed from the installed sys/stat.h header file. The wrapper implementation license LGPL exception is also removed since it is no longer statically linked to binaries.

The internal defines that redirects internals {f}stat{at} to their {f}xstat{at} counterparts are removed for Linux (!NO_RTLD_HIDDEN).

* Fix -Os feof_unlocked linknamespace, localplt issues (bug 15105, bug 19463).Joseph Myers2018-02-151-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the fixes for linknamespace and localplt test failures with -Os that arise from functions not being inlined in that case, this patch fixes such failures for feof_unlocked. The usual approach is followed of adding __feof_unlocked (inlined when feof_unlocked is), making calls use it when required for namespace reasons, and using libc_hidden_proto / libc_hidden_weak for the feof_unlocked weak alias when only localplt but not namespace issues are involved. In the case of getaddrinfo.c, use of __feof_unlocked needs to be conditional since that code is also used in nscd (where __feof_unlocked is not available). Tested for x86_64 (both without -Os to make sure that case continues to work, and with -Os to make sure all the relevant linknamespace and localplt test failures are resolved). Because of other such failures that remain after this patch, neither of the bugs can yet be closed.

For non cancellable targets it will be just a macro to call the default respective symbol while on Linux will be a internal one. Also, since it is used on libcrypto it is also exported in GLIBC_PRIVATE namespace. Checked on x86_64-linux-gnu, x86_64-linux-gnu-x32, and i686-linux-gnu. * sysdeps/generic/not-cancel.h (close_not_cancel): Remove macro. (close_not_cancel_no_status): Likewise.
