Date: Tue, 8 Sep 2015 13:02:44 +0530 From: Huzaifa Sidhpurwala <huzaifas@...hat.com> To: oss-security@...ts.openwall.com, Mitre CVE assign department <cve-assign@...re.org> Subject: Pending CVE requests for glibc Hi MITRE, I could not help but notice, some glibc security issues were not assigned CVE ids. 1. glibc: multiple overflows in strxfrm() Integer overflow when computing memory allocation sizes (similar to CVE-2012-4412) was reported  in glibc strxfrm() function. Attached strxfrm-int32.c should trigger this issue on a 32-bit systems. Additionally, it was discovered  that strxfrm() falls back to an unbounded alloca if malloc fails making it vulnerable to stack-based buffer overflows (similar to CVE-2012-4424). Attached strxfrm-alloca.c should trigger this issue. Previously a request was made via: http://seclists.org/oss-sec/2015/q1/540 2. glibc: _IO_wstr_overflow integer overflow An integer overflow flaw, leading to a heap-based buffer overflow, was found in glibc's _IO_wstr_overflow() function. If an application used this function, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. https://sourceware.org/bugzilla/show_bug.cgi?id=17269 https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=bdf1ff052a8e23d637f2c838fa5642d78fcedc33 3. glibc: potential denial of service in internal_fnmatch() It was reported  that when processing certain malformed patterns, fnmatch can skip over the NUL byte terminating the pattern. This can potentially result in an application crash if fnmatch hits an unmapped page before encountering a NUL byte. https://sourceware.org/bugzilla/show_bug.cgi?id=18032 https://sourceware.org/git/gitweb.cgi?p=glibc.git;h=4a28f4d55a6cc33474c0792fe93b5942d81bf185 Previously a request was made via: http://seclists.org/oss-sec/2015/q1/689 4. glibc: potential denial of service in pop_fail_stack() A crash was reported  during glibc extended regular expression processing. No known patch exists at the time of writing. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=779392 Can MITRE please assign CVE ids to these flaws?
