CVE-2017-1000410 3 Debian, Linux, Redhat 9 Debian Linux, Linux Kernel, Enterprise Linux Desktop and 6 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. By manipulating the code flows that precede the handling of these configuration messages, an attacker can also gain some control over which data will be held in the uninitialized stack variables. This can allow him to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in this manner. Combining this vulnerability (for example) with the previously disclosed RCE vulnerability in L2CAP configuration parsing (CVE-2017-1000251) may allow an attacker to exploit the RCE against kernels which were built with the above mitigations. These are the specifics of this vulnerability: In the function l2cap_parse_conf_rsp and in the function l2cap_parse_conf_req the following variable is declared without initialization: struct l2cap_conf_efs efs; In addition, when parsing input configuration parameters in both of these functions, the switch case for handling EFS elements may skip the memcpy call that will write to the efs variable: ... case L2CAP_CONF_EFS: if (olen == sizeof(efs)) memcpy(&efs, (void *)val, olen); ... The olen in the above if is attacker controlled, and regardless of that if, in both of these functions the efs variable would eventually be added to the outgoing configuration request that is being built: l2cap_add_conf_opt(&ptr, L2CAP_CONF_EFS, sizeof(efs), (unsigned long) &efs); So by sending a configuration request, or response, that contains an L2CAP_CONF_EFS element, but with an element length that is not sizeof(efs) - the memcpy to the uninitialized efs variable can be avoided, and the uninitialized variable would be returned to the attacker (16 bytes).
CVE-2017-1000407 4 Canonical, Debian, Linux and 1 more 10 Ubuntu Linux, Debian Linux, Linux Kernel and 7 more 2024-11-21 6.1 MEDIUM 7.4 HIGH
The Linux Kernel 2.6.32 and later are affected by a denial of service, by flooding the diagnostic port 0x80 an exception can be triggered leading to a kernel panic.
CVE-2017-1000366 8 Debian, Gnu, Mcafee and 5 more 20 Debian Linux, Glibc, Web Gateway and 17 more 2024-11-21 7.2 HIGH 7.8 HIGH
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.
CVE-2017-1000251 4 Debian, Linux, Nvidia and 1 more 10 Debian Linux, Linux Kernel, Jetson Tk1 and 7 more 2024-11-21 7.7 HIGH 8.0 HIGH
The native Bluetooth stack in the Linux Kernel (BlueZ), starting at the Linux kernel version 2.6.32 and up to and including 4.13.1, are vulnerable to a stack overflow vulnerability in the processing of L2CAP configuration responses resulting in Remote code execution in kernel space.
CVE-2017-1000116 3 Debian, Mercurial, Redhat 8 Debian Linux, Mercurial, Enterprise Linux Desktop and 5 more 2024-11-21 10.0 HIGH 9.8 CRITICAL
Mercurial prior to 4.3 did not adequately sanitize hostnames passed to ssh, leading to possible shell-injection attacks.
CVE-2017-1000115 3 Debian, Mercurial, Redhat 8 Debian Linux, Mercurial, Enterprise Linux Desktop and 5 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
Mercurial prior to version 4.3 is vulnerable to a missing symlink check that can malicious repositories to modify files outside the repository
CVE-2017-1000111 3 Debian, Linux, Redhat 9 Debian Linux, Linux Kernel, Enterprise Linux and 6 more 2024-11-21 7.2 HIGH 7.8 HIGH
Linux kernel: heap out-of-bounds in AF_PACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packet_set_ring. Previously with PACKET_VERSION. This time with PACKET_RESERVE. The solution is similar: lock the socket for the update. This issue may be exploitable, we did not investigate further. As this issue affects PF_PACKET sockets, it requires CAP_NET_RAW in the process namespace. But note that with user namespaces enabled, any process can create a namespace in which it has CAP_NET_RAW.
CVE-2017-1000083 3 Debian, Gnome, Redhat 8 Debian Linux, Evince, Enterprise Linux Desktop and 5 more 2024-11-21 6.8 MEDIUM 7.8 HIGH
backend/comics/comics-document.c (aka the comic book backend) in GNOME Evince before 3.24.1 allows remote attackers to execute arbitrary commands via a .cbt file that is a TAR archive containing a filename beginning with a "--" command-line option substring, as demonstrated by a --checkpoint-action=exec=bash at the beginning of the filename.
CVE-2017-0903 4 Canonical, Debian, Redhat and 1 more 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
RubyGems versions between 2.0.0 and 2.6.13 are vulnerable to a possible remote code execution vulnerability. YAML deserialization of gem specifications can bypass class white lists. Specially crafted serialized objects can possibly be used to escalate to remote code execution.
CVE-2017-0902 4 Canonical, Debian, Redhat and 1 more 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more 2024-11-21 6.8 MEDIUM 8.1 HIGH
RubyGems version 2.6.12 and earlier is vulnerable to a DNS hijacking vulnerability that allows a MITM attacker to force the RubyGems client to download and install gems from a server that the attacker controls.
CVE-2017-0901 4 Canonical, Debian, Redhat and 1 more 9 Ubuntu Linux, Debian Linux, Enterprise Linux Desktop and 6 more 2024-11-21 6.4 MEDIUM 7.5 HIGH
RubyGems version 2.6.12 and earlier fails to validate specification names, allowing a maliciously crafted gem to potentially overwrite any file on the filesystem.
CVE-2017-0900 3 Debian, Redhat, Rubygems 8 Debian Linux, Enterprise Linux Desktop, Enterprise Linux Server and 5 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
RubyGems version 2.6.12 and earlier is vulnerable to maliciously crafted gem specifications to cause a denial of service attack against RubyGems clients who have issued a `query` command.
CVE-2017-0899 3 Debian, Redhat, Rubygems 8 Debian Linux, Enterprise Linux Desktop, Enterprise Linux Server and 5 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
RubyGems version 2.6.12 and earlier is vulnerable to maliciously crafted gem specifications that include terminal escape characters. Printing the gem specification would execute terminal escape sequences.
CVE-2016-9902 2 Mozilla, Redhat 7 Firefox, Firefox Esr, Enterprise Linux Desktop and 4 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
The Pocket toolbar button, once activated, listens for events fired from it's own pages but does not verify the origin of incoming events. This allows content from other origins to fire events and inject content and commands into the Pocket context. Note: this issue does not affect users with e10s enabled. This vulnerability affects Firefox ESR < 45.6 and Firefox < 50.1.
CVE-2016-9900 3 Debian, Mozilla, Redhat 10 Debian Linux, Firefox, Firefox Esr and 7 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
External resources that should be blocked when loaded by SVG images can bypass security restrictions through the use of "data:" URLs. This could allow for cross-domain data leakage. This vulnerability affects Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6.
CVE-2016-9899 3 Debian, Mozilla, Redhat 10 Debian Linux, Firefox, Firefox Esr and 7 more 2024-11-21 7.5 HIGH 9.8 CRITICAL

CVE-2016-9893 3 Debian, Mozilla, Redhat 10 Debian Linux, Firefox, Firefox Esr and 7 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
Memory safety bugs were reported in Thunderbird 45.5. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6.
CVE-2016-9603 4 Citrix, Debian, Qemu and 1 more 9 Xenserver, Debian Linux, Qemu and 6 more 2024-11-21 9.0 HIGH 5.5 MEDIUM
A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest. A privileged user/process inside a guest could use this flaw to crash the QEMU process or, potentially, execute arbitrary code on the host with privileges of the QEMU process.
