CVSS: 4.3EPSS: 0%CPEs: 8EXPL: 0CVE-2014-3479 – file: cdf_check_stream_offset insufficient boundary check
https://notcve.org/view.php?id=CVE-2014-3479
The cdf_check_stream_offset function in cdf.c in file before 5.19, as used in the Fileinfo component in PHP before 5.4.30 and 5.5.x before 5.5.14, relies on incorrect sector-size data, which allows remote attackers to cause a denial of service (application crash) via a crafted stream offset in a CDF file. La función cdf_check_stream_offset en cdf.c en file anterior a 5.19, utilizado en el componente Fileinfo en PHP anterior a 5.4.30 y 5.5.x anterior a 5.5.14, depende de datos de tamaño de sectores incorrectos, lo que permite a atacantes remotos causar una denegación de servicio (caída de aplicación) a través de un desplazamiento de flujo manipulado en un fichero CDF. A denial of service flaw was found in the way the File Information (fileinfo) extension parsed certain Composite Document Format (CDF) files. A remote attacker could use this flaw to crash a PHP application using fileinfo via a specially crafted CDF file. • http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://lists.opensuse.org/opensuse-updates/2014-09/msg00046.html http://marc.info/?l=bugtraq&m=141017844705317&w=2 http://mx.gw.com/pipermail/file/2014/001553.html http://rhn.redhat.com/errata/RHSA-2014-1765.html http://rhn.redhat.com/errata/RHSA-2014-1766.html http://secunia.com/advisories/59794 http://secunia.com/advisories/59831 http://support.apple.com/kb/HT6443 http://www.debian.org/ •
CVSS: 5.0EPSS: 1%CPEs: 23EXPL: 4CVE-2014-3538 – file: unrestricted regular expression matching
https://notcve.org/view.php?id=CVE-2014-3538
file before 5.19 does not properly restrict the amount of data read during a regex search, which allows remote attackers to cause a denial of service (CPU consumption) via a crafted file that triggers backtracking during processing of an awk rule. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-7345. file anterior a 5.19 no restringe debidamente la cantidad de datos leídos durante una búsqueda regex, lo que permite a atacantes remotos causar una denegación de servicio (consumo de CPU) a través de un fichero manipulado que provoca un retroceso durante el procesamiento de una norma awk. NOTA: esta vulnerabilidad existe debido a una soluciona incompleta para CVE-2013-7345. Multiple flaws were found in the File Information (fileinfo) extension regular expression rules for detecting various files. A remote attacker could use either of these flaws to cause a PHP application using fileinfo to consume an excessive amount of CPU. • http://lists.apple.com/archives/security-announce/2015/Apr/msg00001.html http://mx.gw.com/pipermail/file/2014/001553.html http://openwall.com/lists/oss-security/2014/06/30/7 http://rhn.redhat.com/errata/RHSA-2014-1327.html http://rhn.redhat.com/errata/RHSA-2014-1765.html http://rhn.redhat.com/errata/RHSA-2014-1766.html http://rhn.redhat.com/errata/RHSA-2016-0760.html http://secunia.com/advisories/60696 http://www.debian.org/security/2014/dsa-3008 http:/ • CWE-399: Resource Management Errors •
CVSS: 5.0EPSS: 0%CPEs: 6EXPL: 2CVE-2013-7345 – file: extensive backtracking in awk rule regular expression
https://notcve.org/view.php?id=CVE-2013-7345
The BEGIN regular expression in the awk script detector in magic/Magdir/commands in file before 5.15 uses multiple wildcards with unlimited repetitions, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted ASCII file that triggers a large amount of backtracking, as demonstrated via a file with many newline characters. La expresión regular BEGIN en el detector de script de awk en el archivo magic/Magdir/commands anterior a 5.15 utiliza múltiples comodines con repeticiones ilimitadas, lo que permite a atacantes dependientes de contexto causar una denegación de servicio (consumo de CPU) a través de un archivo ASCII manipulado que provoca una gran cantidad de retroceso, como se demostró a través de un archivo con muchos caracteres de nueva línea. A denial of service flaw was found in the File Information (fileinfo) extension rules for detecting AWK files. A remote attacker could use this flaw to cause a PHP application using fileinfo to consume an excessive amount of CPU. • http://bugs.gw.com/view.php?id=164 http://rhn.redhat.com/errata/RHSA-2014-1765.html http://support.apple.com/kb/HT6443 http://www.debian.org/security/2014/dsa-2873 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=703993 https://github.com/file/file/commit/ef2329cf71acb59204dd981e2c6cce6c81fe467c https://access.redhat.com/security/cve/CVE-2013-7345 https://bugzilla.redhat.com/show_bug.cgi?id=1079846 • CWE-407: Inefficient Algorithmic Complexity •
