CVSS: 6.4EPSS: 0%CPEs: 5EXPL: 0CVE-2015-1473 – glibc: Stack-overflow in glibc swscanf
https://notcve.org/view.php?id=CVE-2015-1473
The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during a risk-management decision for use of the alloca function, which might allow context-dependent attackers to cause a denial of service (segmentation violation) or overwrite memory locations beyond the stack boundary via a long line containing wide characters that are improperly handled in a wscanf call. El macro ADDW en stdio-common/vfscanf.c en la libraría GNU C (también conocida como glibc o libc6) anterior a 2.21 no considera correctamente el tamaño de tipos de datos durante una decisión de la gestión de riesgos para utilizar en la función alloca, lo que podría permitir atacantes dependientes de contexto causar una denegación de servicio (violación de segmentación) o sobrescribir localizaciones de memoria más allá del límite de la pila a través de una línea larga que contiene caracateres anchas que se manejen incorrectamente en una llamada wscanf. A stack overflow flaw was found in glibc's swscanf() function. An attacker able to make an application call the swscanf() function could use this flaw to crash that application or, potentially, execute arbitrary code with the permissions of the user running the application. • http://openwall.com/lists/oss-security/2015/02/04/1 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2015-2719645.html http://www.securityfocus.com/bid/72499 http://www.ubuntu.com/usn/USN-2519-1 https://sourceware.org/git/gitweb.cgi?p=glibc.git%3Ba=commit%3Bh=5bd80bfe9ca0d955bfbbc002781bc7b01b6bcb06 https://access.redhat.com/security/cve/CVE-2015-1473 https://bugzilla.redhat.com/show_bug.cgi?id=1209105 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •

The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during memory allocation, which allows context-dependent attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a long line containing wide characters that are improperly handled in a wscanf call. El macro ADDW en stdio-common/vfscanf.c en la libraría GNU C (también conocida como glibc o libc6) anterior a 2.21 no considera correctamente el tamaño de datos de estado durante la reserva de memoria, lo que permite a atacantes dependientes de contexto causar una denegación de servicio (desbordamiento de buffer) o posiblemente tener otro impacto no especificado a través de una línea larga que contiene caracteres anchos que se manejen incorrectamente en una llamada wscanf. A heap-based buffer overflow flaw was found in glibc's swscanf() function. An attacker able to make an application call the swscanf() function could use this flaw to crash that application or, potentially, execute arbitrary code with the permissions of the user running the application.

https://notcve.org/view.php?id=CVE-2014-6040
GNU C Library (aka glibc) before 2.20 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via a multibyte character value of "0xffff" to the iconv function when converting (1) IBM933, (2) IBM935, (3) IBM937, (4) IBM939, or (5) IBM1364 encoded data to UTF-8. GNU C Library (también conocido como glibc) anterior a 2.20 permite a atacantes dependientes de contexto causar una denegación de servicio (lectura fuera de rango y caída) a través de un valor de caracteres de multibytes de '0xffff' en la función iconv cuando convierte datos codificados de (1) IBM933, (2) IBM935, (3) IBM937, (4) IBM939, o (5) IBM1364 a UTF-8. An out-of-bounds read flaw was found in the way glibc's iconv() function converted certain encoded data to UTF-8. An attacker able to make an application call the iconv() function with a specially crafted argument could use this flaw to crash that application. • http://linux.oracle.com/errata/ELSA-2015-0016.html http://secunia.com/advisories/62100 http://secunia.com/advisories/62146 http://ubuntu.com/usn/usn-2432-1 http://www.debian.org/security/2015/dsa-3142 http://www.mandriva.com/security/advisories?name=MDVSA-2014:175 http://www.openwall.com/lists/oss-security/2014/08/29/3 http://www.openwall.com/lists/oss-security/2014/09/02/1 http://www.securityfocus.com/bid/69472 https://security.gentoo.org/glsa/201602-02& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
