CVE-2014-7169 17 Apple, Arista, Canonical and 14 more 85 Mac Os X, Eos, Ubuntu Linux and 82 more 2025-04-12 10.0 HIGH 9.8 CRITICAL
GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.

Use-after-free vulnerability in hw/ide/ahci.c in QEMU, when built with IDE AHCI Emulation support, allows guest OS users to cause a denial of service (instance crash) or possibly execute arbitrary code via an invalid AHCI Native Command Queuing (NCQ) AIO command.
CVE-2016-5126 5 Canonical, Debian, Oracle and 2 more 13 Ubuntu Linux, Debian Linux, Linux and 10 more 2025-04-12 4.6 MEDIUM 7.8 HIGH
Heap-based buffer overflow in the iscsi_aio_ioctl function in block/iscsi.c in QEMU allows local guest OS users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code via a crafted iSCSI asynchronous I/O ioctl call.
CVE-2014-3468 5 Debian, F5, Gnu and 2 more 16 Debian Linux, Arx, Arx Firmware and 13 more 2025-04-12 7.5 HIGH N/A
The asn1_get_bit_der function in GNU Libtasn1 before 3.6 does not properly report an error when a negative bit length is identified, which allows context-dependent attackers to cause out-of-bounds access via crafted ASN.1 data.
