Mozilla: Miscellaneous memory safety hazards (rv:47.0) (MFSA 2016-49)

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 47.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Mozilla: Caret character improperly escaped in origins

A vulnerability exists where the caret ("^") character is improperly escaped constructing some URIs due to it being used as a separator, allowing for possible spoofing of origin attributes. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.

ntp: 'ntpq saveconfig' command allows dangerous characters in filenames

The ntpq saveconfig command in NTP 4.1.2, 4.2.x before 4.2.8p6, 4.3, 4.3.25, 4.3.70, and 4.3.77 does not properly filter special characters, which allows attackers to cause unspecified impact via a crafted filename.

kexec-tools: mkdumprd script called "dracut" in the current working directory

The mkdumprd script called "dracut" in the current working directory "." allows local users to trick the administrator into executing code as root.

game-music-emu before 0.6.1 allows local users to cause a denial of service (divide by zero and process crash).

game-music-emu before 0.6.1 mishandles unspecified integer values.

ImageMagick: memory leak in rle file handling

Memory leak in coders/rle.c in ImageMagick allows remote attackers to cause a denial of service (memory consumption) via a crafted rle file.

dnsmasq: Size parameter overflow via large DNS query

In dnsmasq before 2.78, if the DNS packet size does not match the expected size, the size parameter in a memset call gets a negative value. As it is an unsigned value, memset ends up writing up to 0xffffffff zero's (0xffffffffffffffff in 64 bit platforms), making dnsmasq crash.

dnsmasq: heap overflow in the IPv6 router advertisement code

Heap-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted IPv6 router advertisement request.

dnsmasq: information leak in the DHCPv6 relay code

dnsmasq before 2.78, when configured as a relay, allows remote attackers to obtain sensitive memory information via vectors involving handling DHCPv6 forwarded requests.

dnsmasq: memory exhaustion vulnerability in the EDNS0 code

Memory leak in dnsmasq before 2.78, when the --add-mac, --add-cpe-id or --add-subnet option is specified, allows remote attackers to cause a denial of service (memory consumption) via vectors involving DNS response creation.

dnsmasq: integer underflow leading to buffer over-read in the EDNS0 code

Integer underflow in the add_pseudoheader function in dnsmasq before 2.78 , when the --add-mac, --add-cpe-id or --add-subnet option is specified, allows remote attackers to cause a denial of service via a crafted DNS request.

golang: Elliptic curves carry propagation issue in x86-64 P-256

A bug in the standard library ScalarMult implementation of curve P-256 for amd64 architectures in Go before 1.7.6 and 1.8.x before 1.8.2 causes incorrect results to be generated for specific input points. An adaptive attack can be mounted to progressively extract the scalar input to ScalarMult by submitting crafted points and observing failures to the derive correct output. This leads to a full key recovery attack against static ECDH, as used in popular JWT libraries.

glibc: heap/stack gap jumping via unbounded stack allocations

glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier.

ntp: infinite loop in sntp processing crafted packet

The ULOGTOD function in ntp.d in SNTP before 4.2.7p366 does not properly perform type conversions from a precision value to a double, which allows remote attackers to cause a denial of service (infinite loop) via a crafted NTP packet.

ntp: crypto-NAK DoS (incorrect fix for CVE-2016-1547)

ntpd in NTP before 4.2.8p8 allows remote attackers to cause a denial of service (daemon crash) via a crypto-NAK packet. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-1547.

The parse_string function in cjson.c in the cJSON library mishandles UTF8/16 strings, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a non-hex character in a JSON string, which triggers a heap-based buffer overflow.

chromium-browser: same-origin bypass in Blink and Sandbox escape in Chrome

Google Chrome before 48.0.2564.116 allows remote attackers to bypass the Blink Same Origin Policy and a sandbox protection mechanism via unspecified vectors.

chromium-browser: address bar spoofing

The WebContentsImpl::FocusLocationBarByDefault function in content/browser/web_contents/web_contents_impl.cc in Google Chrome before 50.0.2661.75 mishandles focus for certain about:blank pages, which allows remote attackers to spoof the address bar via a crafted URL.

chromium-browser: potential leak of sensitive information to malicious extensions

The Extensions subsystem in Google Chrome before 50.0.2661.75 incorrectly relies on GetOrigin method calls for origin comparisons, which allows remote attackers to bypass the Same Origin Policy and obtain sensitive information via a crafted extension.
