CVE-2018-1000156 – patch: Malicious patch files cause ed to execute arbitrary commands
https://notcve.org/view.php?id=CVE-2018-1000156
GNU Patch version 2.7.6 contains an input validation vulnerability when processing patch files, specifically the EDITOR_PROGRAM invocation (using ed) can result in code execution. This attack appear to be exploitable via a patch file processed via the patch utility. This is similar to FreeBSD's CVE-2015-1418 however although they share a common ancestry the code bases have diverged over time. La versión 2.7.6 de GNU Patch contiene una vulnerabilidad de validación de entradas al procesar archivos patch; específicamente la invocación EDITOR_PROGRAM (usando ed) puede resultar en la ejecución de código. el ataque parece ser explotable mediante un archivo patch procesado mediante la utilidad patch. Esto es similar al CVE-2015-1418 de FreeBSD: aunque comparten un ancestro común, las bases de código han divergido con el tiempo. • http://packetstormsecurity.com/files/154124/GNU-patch-Command-Injection-Directory-Traversal.html http://rachelbythebay.com/w/2018/04/05/bangpatch https://access.redhat.com/errata/RHSA-2018:1199 https://access.redhat.com/errata/RHSA-2018:1200 https://access.redhat.com/errata/RHSA-2018:2091 https://access.redhat.com/errata/RHSA-2018:2092 https://access.redhat.com/errata/RHSA-2018:2093 https://access.redhat.com/errata/RHSA-2018:2094 https://access.redhat.com/errata/RHSA-2018:2095 ht • CWE-20: Improper Input Validation CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •
CVE-2018-7566 – kernel: race condition in snd_seq_write() may lead to UAF or OOB-access
https://notcve.org/view.php?id=CVE-2018-7566
The Linux kernel 4.15 has a Buffer Overflow via an SNDRV_SEQ_IOCTL_SET_CLIENT_POOL ioctl write operation to /dev/snd/seq by a local user. El kernel de Linux 4.15 tiene un desbordamiento de búfer mediante una operación de escritura ioctl SNDRV_SEQ_IOCTL_SET_CLIENT_POOL en /dev/snd/seq por un usuario local. ALSA sequencer core initializes the event pool on demand by invoking snd_seq_pool_init() when the first write happens and the pool is empty. A user can reset the pool size manually via ioctl concurrently, and this may lead to UAF or out-of-bound access. • http://lists.opensuse.org/opensuse-security-announce/2018-03/msg00067.html http://mailman.alsa-project.org/pipermail/alsa-devel/2018-February/132026.html http://www.securityfocus.com/bid/103605 https://access.redhat.com/errata/RHSA-2018:2384 https://access.redhat.com/errata/RHSA-2018:2390 https://access.redhat.com/errata/RHSA-2018:2395 https://access.redhat.com/errata/RHSA-2018:2948 https://access.redhat.com/errata/RHSA-2019:1483 https://access.redhat.com/errata/RHSA-2019:1487 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2018-1312 – httpd: Weak Digest auth nonce generation in mod_auth_digest
https://notcve.org/view.php?id=CVE-2018-1312
In Apache httpd 2.2.0 to 2.4.29, when generating an HTTP Digest authentication challenge, the nonce sent to prevent reply attacks was not correctly generated using a pseudo-random seed. In a cluster of servers using a common Digest authentication configuration, HTTP requests could be replayed across servers by an attacker without detection. En Apache httpd, en versiones desde la 2.2.0 hasta la 2.4.29, cuando se genera un desafío de autenticación HTTP Digest, el nonce enviado para evitar ataques replay no se generó correctamente empleando una semilla pseudoaleatoria. En un clúster de servidores, utilizando una configuración de autenticación Digest común, las peticiones HTTP se podrían reemplazar en los servidores por un atacante si que este sea detectado. • http://www.openwall.com/lists/oss-security/2018/03/24/7 http://www.securityfocus.com/bid/103524 http://www.securitytracker.com/id/1040571 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2019:0366 https://access.redhat.com/errata/RHSA-2019:0367 https://access.redhat.com/errata/RHSA-2019:1898 https://httpd.apache.org/security/vulnerabilities_24.html https://lists.apache.org/thread.html/56c2e7cc9deb1c12a843d0dc251ea7fd3e7e80293cde02fcd65286ba%40%3Ccvs.httpd. • CWE-287: Improper Authentication CWE-305: Authentication Bypass by Primary Weakness •
CVE-2018-1000140 – librelp: Stack-based buffer overflow in relpTcpChkPeerName function in src/tcp.c
https://notcve.org/view.php?id=CVE-2018-1000140
rsyslog librelp version 1.2.14 and earlier contains a Buffer Overflow vulnerability in the checking of x509 certificates from a peer that can result in Remote code execution. This attack appear to be exploitable a remote attacker that can connect to rsyslog and trigger a stack buffer overflow by sending a specially crafted x509 certificate. rsyslog librelp en versiones 1.2.14 y anteriores contiene una vulnerabilidad de desbordamiento de búfer en la verificación de certificados x509 desde un peer que puede resultar en la ejecución remota de código. Parece que este ataque puede ser explotable debido a que un atacante remoto puede conectarse a rsyslog y desencadena un desbordamiento de búfer basado en pila mediante el envío de un certificado x509 especialmente manipulado. A stack-based buffer overflow was found in the way librelp parses X.509 certificates. By connecting or accepting connections from a remote peer, an attacker may use a specially crafted X.509 certificate to exploit this flaw and potentially execute arbitrary code. • https://github.com/s0/rsyslog-librelp-CVE-2018-1000140 https://github.com/s0/rsyslog-librelp-CVE-2018-1000140-fixed http://packetstormsecurity.com/files/172829/librelp-Remote-Code-Execution.html https://access.redhat.com/errata/RHSA-2018:1223 https://access.redhat.com/errata/RHSA-2018:1225 https://access.redhat.com/errata/RHSA-2018:1701 https://access.redhat.com/errata/RHSA-2018:1702 https://access.redhat.com/errata/RHSA-2018:1703 https://access.redhat.com/errata/RHSA-2018:1704 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
