+ * The LD_POINTER_GUARD environment variable can no longer be used to
+ disable the pointer guard feature. It is always enabled.
+
+* CVE-2014-8121 The NSS backends shared internal state between the getXXent
+ and getXXbyYY NSS calls for the same database, causing a denial-of-service
+ condition in some applications.
+
+* A buffer overflow in gethostbyname_r and related functions performing DNS
+ requests has been fixed. If the NSS functions were called with a
+ misaligned buffer, the buffer length change due to pointer alignment was
+ not taken into account. This could result in application crashes or,
+ potentially arbitrary code execution, using crafted, but syntactically
+ valid DNS responses. (CVE-2015-1781)
+
+* Support for powerpc64le has been added.
+
+* CVE-2104-7817 The wordexp function could ignore the WRDE_NOCMD flag
+ under certain input conditions resulting in the execution of a shell for
+ command substitution when the applicaiton did not request it. The
+ implementation now checks WRDE_NOCMD immediately before executing the
+ shell and returns the error WRDE_CMDSUB as expected.
+
+* CVE-2012-3406 printf-style functions could run into a stack overflow when
+ processing format strings with a large number of format specifiers.
+
+* CVE-2014-9402 The nss_dns implementation of getnetbyname could run into an
+ infinite loop if the DNS response contained a PTR record of an unexpected
+ format.
+
+* CVE-2014-4043 The posix_spawn_file_actions_addopen implementation did not
+ copy the path argument. This allowed programs to cause posix_spawn to
+ deference a dangling pointer, or use an unexpected pathname argument if
+ the string was modified after the posix_spawn_file_actions_addopen
+ invocation.
+
+* Locale names, including those obtained from environment variables (LANG
+ and the LC_* variables), are more tightly checked for proper syntax.
+ setlocale will now fail (with EINVAL) for locale names that are overly
+ long, contain slashes without starting with a slash, or contain ".." path
+ components. (CVE-2014-0475) Previously, some valid locale names were
+ silently replaced with the "C" locale when running in AT_SECURE mode
+ (e.g., in a SUID program). This is no longer necessary because of the
+ additional checks.
+
+* Support for loadable gconv transliteration modules has been removed.
+ The support for transliteration modules has been non-functional for
+ over a decade, and the removal is prompted by security defects. The
+ normal gconv conversion modules are still supported. Transliteration
+ with //TRANSLIT is still possible, and the //IGNORE specifier
+ continues to be supported. (CVE-2014-5119)
+
+* Decoding a crafted input sequence in the character sets IBM933, IBM935,
+ IBM937, IBM939, IBM1364 could result in an out-of-bounds array read,
+ resulting a denial-of-service security vulnerability in applications which
+ use functions related to iconv. (CVE-2014-6040)
+
+* CVE-2013-4237 The readdir_r function could write more than NAME_MAX bytes
+ to the d_name member of struct dirent, or omit the terminating NUL
+ character. (Bugzilla #14699).
+
+* CVE-2013-4458 Stack overflow in getaddrinfo with large number of results
+ for AF_INET6 has been fixed (Bugzilla #16072).
+
+* CVE-2013-4332 The pvalloc, valloc, memalign, posix_memalign and
+ aligned_alloc functions could allocate too few bytes or corrupt the
+ heap when passed very large allocation size values (Bugzilla #15855,
+ #15856, #15857).
+
+* CVE-2012-4424 The strcoll implementation uses malloc to cache indices and
+ rules for large collation sequences to optimize multiple passes and falls
+ back to alloca if malloc fails, resulting in a possible stack overflow.
+ The implementation now falls back to an uncached collation sequence lookup
+ if malloc fails.
