+X-Git-Url: https://sourceware.org/git/gitweb.cgi?p=glibc.git;a=commitdiff_plain;h=33ceaf6187b31ea15284ac65131749e1cb68d2ae
+
+CVE-2014-7817: wordexp fails to honour WRDE_NOCMD.
+
+The function wordexp() fails to properly handle the WRDE_NOCMD
+flag when processing arithmetic inputs in the form of "$((... ``))"
+where "..." can be anything valid. The backticks in the arithmetic
+epxression are evaluated by in a shell even if WRDE_NOCMD forbade
+command substitution. This allows an attacker to attempt to pass
+dangerous commands via constructs of the above form, and bypass
+the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD
+in exec_comm(), the only place that can execute a shell. All other
+checks for WRDE_NOCMD are superfluous and removed.
+
+We expand the testsuite and add 3 new regression tests of roughly
+the same form but with a couple of nested levels.
+
+On top of the 3 new tests we add fork validation to the WRDE_NOCMD
+testing. If any forks are detected during the execution of a wordexp()
+call with WRDE_NOCMD, the test is marked as failed. This is slightly
+heuristic since vfork might be used in the future, but it provides a
+higher level of assurance that no shells were executed as part of
+command substitution with WRDE_NOCMD in effect. In addition it doesn't
+require libpthread or libdl, instead we use the public implementation
+namespace function __register_atfork (already part of the public ABI
+for libpthread).
+
+Tested on x86_64 with no regressions.
+

+Subject: MIPS: Avoid a dangling `vfork@GLIBC_2.0' reference
+X-Git-Url: https://sourceware.org/git/?p=glibc.git;a=commitdiff_plain;h=c14e752fc73d34c75d4f84f37fea8e0b1734cf98
+
+MIPS: Avoid a dangling `vfork@GLIBC_2.0' reference
+
+This satisfies a symbol reference created with:
+
+	.symver	__libc_vfork, vfork@GLIBC_2.0
+
+where `__libc_vfork' has not been defined or referenced.  In this case
+the `vfork@GLIBC_2.0' reference is supposed to be discarded, however a
+bug present in GAS since forever causes an undefined symbol table entry
+to be created.  This in turn triggers a problem in the linker that can
+manifest itself by link errors such as:
+
+ld: libpthread.so: invalid string offset 2765592330 >= 5154 for section `.dynstr'
+
+The GAS and linker bugs need to be resolved, but we can avoid them too
+by providing a `__libc_vfork' definition just like our other platforms.
+
+	[BZ #17485]
+	* sysdeps/unix/sysv/linux/mips/vfork.S (__libc_vfork): Define.

+Rework the growing algorithm in patchelf to support ARM systems.

+Subject: [PATCH] Rework the growing algorithm
+
+On ARM systems there is no space in virtual memory for another LOAD
+area in front of the code LOAD area. So insert data to its end
+instead. At this location there should be enough space in virtual
+memory due to alignment. We can extend it until the end of the
+alignment but the file shift may be greater as it must be aligned
+to the page size. Do the same for the data LOAD area.
