* Fix stack overflow due to large AF_INET6 requests archlinux/2.18/masterSiddhesh Poyarekar2013-10-252-2/+24
| | | | | | | | | | | | | Resolves #16072 (CVE-2013-4458). This patch fixes another stack overflow in getaddrinfo when it is called with AF_INET6. The AF_UNSPEC case was fixed as CVE-2013-1914, but the AF_INET6 case went undetected back then. (cherry picked from commit 7cbcdb3699584db8913ca90f705d6337633ee10f) Conflicts: NEWS
* Fix incorrect getaddrinfo assertion triggerAllan McRae2013-10-252-3/+18
| | | | | | | | | | | | | | | | | | | | | [BZ #9954] With the following /etc/hosts: 127.0.0.1 www.my-domain.es 127.0.1.1 www.my-domain.es 192.168.0.1 www.my-domain.es Using getaddrinfo() on www.my-domain.es, trigger the following assertion: ../sysdeps/posix/getaddrinfo.c:1473: rfc3484_sort: Assertion `src->results[i].native == -1 || src->results[i].native == a1_native' failed. This is due to two different bugs: - In rfc3484_sort() rule 7, src->results[i].native is assigned even if src->results[i].index is -1, meaning that no interface is associated. - In getaddrinfo() the source IP address used with the lo interface needs a special case, as it can be any IP within 127.X.Y.Z. (cherry picked from commit 894f3f1049135dcbeaab8f18690973663ef3147c)
* BZ #15754: Fix test case for ARM.Carlos O'Donell2013-10-253-1/+16
| | | | | | | Statically built binaries use __pointer_chk_guard_local, while dynamically built binaries use __pointer_chk_guard. Provide the right definition depending on the test case we are building.
* BZ #15754: CVE-2013-4788Carlos O'Donell2013-10-2518-2/+342
| | | | | | | | | | | | | | | | | The pointer guard used for pointer mangling was not initialized for static applications resulting in the security feature being disabled. The pointer guard is now correctly initialized to a random value for static applications. Existing static applications need to be recompiled to take advantage of the fix. The test tst-ptrguard1-static and tst-ptrguard1 add regression coverage to ensure the pointer guards are sufficiently random and initialized to a default value.

* Check for integer overflow in cache size computation in strcollSiddhesh Poyarekar2013-10-254-1/+80
| | | | | | | | | | | | | | | | strcoll is implemented using a cache for indices and weights of collation sequences in the strings so that subsequent passes do not have to search through collation data again. For very large string inputs, the cache size computation could overflow. In such a case, use the fallback function that does not cache indices and weights of collation sequences. Fixes CVE-2012-4412. (cherry picked from commit 303e567a8062200dc06acde7c76fc34679f08d8f) Conflicts: NEWS
* Fall back to non-cached sequence traversal and comparison on malloc failSiddhesh Poyarekar2013-10-252-31/+244
| | | | | | | | | | | | | strcoll currently falls back to alloca if malloc fails, resulting in a possible stack overflow. This patch implements sequence traversal and comparison without caching indices and rules. Fixes CVE-2012-4424. (cherry picked from commit 141f3a77fe4f1b59b0afa9bf6909cd2000448883) Conflicts: NEWS
* Simplify strcoll implementationSiddhesh Poyarekar2013-10-252-406/+304

* CVE-2013-2207, BZ #15755: Disable pt_chown.Carlos O'Donell2013-07-2111-7/+100
| | | | | | | | | | | | | | | | | | | | | | | The helper binary pt_chown tricked into granting access to another user's pseudo-terminal. Pre-conditions for the attack: * Attacker with local user account * Kernel with FUSE support * "user_allow_other" in /etc/fuse.conf * Victim with allocated slave in /dev/pts Using the setuid installed pt_chown and a weak check on whether a file descriptor is a tty, an attacker could fake a pty check using FUSE and trick pt_chown to grant ownership of a pty descriptor that the current user does not own. It cannot access /dev/pts/ptmx however. In most modern distributions pt_chown is not needed because devpts is enabled by default. The fix for this CVE is to disable building and using pt_chown by default. We still provide a configure option to enable hte use of pt_chown but distributions do so at their own risk.

| | | | | | | | | | | | | | | | | | The generated header is compiled with `-ffreestanding' to avoid any circular dependencies against the installed implementation headers. Such a dependency would require the implementation header to be installed before the generated header could be built (See bug 15711). In current practice the generated header dependencies do not include any of the implementation headers removed by the use of `-ffreestanding'. --- 2013-07-15 Carlos O'Donell <carlos@redhat.com> [BZ #15711] * sysdeps/unix/sysv/linux/Makefile ($(objpfx)bits/syscall%h): Avoid system header dependency with -ffreestanding.
