I'll assign these tomorrow unless Mitre gets to them first, the one request swbz#18928 is already several months old and shouldn't take this long. On Tue, Jan 19, 2016 at 11:04 AM, Florian Weimer <fweimer () redhat com> wrote:
Hi, we are preparing the glibc 2.23 release upstream and have fixed the following security bugs which, to my best knowledge, lack public CVE assignment so far: Passing out of range data to strftime() causes a segfault https://sourceware.org/bugzilla/show_bug.cgi?id=18985 Out-of-range time values passed to the strftime function may cause it to crash, leading to a denial of service, or potentially disclosure information. LD_POINTER_GUARD is not ignored for privileged binaries https://sourceware.org/bugzilla/show_bug.cgi?id=18928 LD_POINTER_GUARD was an environment variable which controls security-related behavior, but was not ignored for privileged binaries (in AT_SECURE mode). This might allow local attackers (who can supply the environment variable) to bypass intended security restrictions. hcreate((size_t)-1) should fail with ENOMEM https://sourceware.org/bugzilla/show_bug.cgi?id=18240 This is an integer overflow in hcreate and hcreate_r which can result in an out-of-bound memory access. This could lead to application crashes or, potentially, arbitrary code execution. nan function unbounded stack allocation https://sourceware.org/bugzilla/show_bug.cgi?id=16962 A stack overflow (unbounded alloca) can cause applications which process long strings with the nan function to crash or, potentially, execute arbitrary code. catopen() Multiple unbounded stack allocations https://sourceware.org/bugzilla/show_bug.cgi?id=17905 A stack overflow (unbounded alloca) in the catopen function can cause applications which pass long strings to the catopen function to crash or, potentially execute arbitrary code. Several people have asked for CVE assignment for swbz#18928 on oss-security already. Thanks, Florian
