CVSS: 5.5EPSS: 0%CPEs: 9EXPL: 0CVE-2014-0148 – Qemu: vhdx: bounds checking for block_size and logical_sector_size
https://notcve.org/view.php?id=CVE-2014-0148
Qemu before 2.0 block driver for Hyper-V VHDX Images is vulnerable to infinite loops and other potential issues when calculating BAT entries, due to missing bounds checks for block_size and logical_sector_size variables. These are used to derive other fields like 'sectors_per_block' etc. A user able to alter the Qemu disk image could ise this flaw to crash the Qemu instance resulting in DoS. El controlador de bloques de Qemu versiones anteriores a 2.0 para imágenes VHDX de Hyper-V es vulnerable a bucles infinitos y otros problemas potenciales cuando son calculadas las entradas BAT, debido a que faltan comprobaciones de límites para las variables block_size y logical_sector_size. Éstas son usadas para derivar otros campos como "sectors_per_block", etc. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=1d7678dec4761acdc43439da6ceda41a703ba1a6 http://rhn.redhat.com/errata/RHSA-2014-0420.html http://rhn.redhat.com/errata/RHSA-2014-0421.html http://www.openwall.com/lists/oss-security/2014/03/26/8 https://bugzilla.redhat.com/show_bug.cgi?id=1078212 https://lists.gnu.org/archive/html/qemu-devel/2014-03/msg04994.html https://access.redhat.com/security/cve/CVE-2014-0148 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVSS: 7.5EPSS: 97%CPEs: 54EXPL: 16CVE-2014-0160 – OpenSSL Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2014-0160
The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug. Las implementaciones de (1) TLS y (2) DTLS en OpenSSL 1.0.1 en versiones anteriores a 1.0.1g no manejan adecuadamente paquetes Heartbeat Extension, lo que permite a atacantes remotos obtener información sensible desde la memoria de proceso a través de paquetes manipulados que desencadenan una sobrelectura del buffer, según lo demostrado mediante la lectura de claves privadas, relacionado con d1_both.c y t1_lib.c, también conocido como bug Heartbleed. An information disclosure flaw was found in the way OpenSSL handled TLS and DTLS Heartbeat Extension packets. A malicious TLS or DTLS client or server could send a specially crafted TLS or DTLS Heartbeat packet to disclose a limited portion of memory per request from a connected client or server. Note that the disclosed portions of memory could potentially include sensitive information such as private keys. • https://www.exploit-db.com/exploits/32764 https://www.exploit-db.com/exploits/32791 https://www.exploit-db.com/exploits/32998 https://www.exploit-db.com/exploits/32745 https://github.com/0x90/CVE-2014-0160 https://github.com/jdauphant/patch-openssl-CVE-2014-0160 https://github.com/caiqiqi/OpenSSL-HeartBleed-CVE-2014-0160-PoC https://github.com/obayesshelton/CVE-2014-0160-Scanner https://github.com/MrE-Fog/CVE-2014-0160-Chrome-Plugin https://github.com/Xyl2k/CVE-2014&# • CWE-125: Out-of-bounds Read CWE-201: Insertion of Sensitive Information Into Sent Data •
