https://notcve.org/view.php?id=CVE-2019-9636
08 Mar 2019 — Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by: Improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization. The impact is: Information disclosure (credentials, cookies, etc. that are cached against a given hostname). The components are: urllib.parse.urlsplit, urllib.parse.urlparse. The attack vector is: A specially crafted URL could be incorrectly parsed to locate cookies or authentication data and send that information to a different host than when parsed c... • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00092.html • CWE-172: Encoding Error •

CVE-2019-6454 – systemd: Insufficient input validation in bus_process_object() resulting in PID 1 crash
https://notcve.org/view.php?id=CVE-2019-6454
18 Feb 2019 — An issue was discovered in sd-bus in systemd 239. bus_process_object() in libsystemd/sd-bus/bus-objects.c allocates a variable-length stack buffer for temporarily storing the object path of incoming D-Bus messages. An unprivileged local user can exploit this by sending a specially crafted message to PID1, causing the stack pointer to jump over the stack guard pages into an unmapped memory region and trigger a denial of service (systemd PID1 crash and kernel panic). Se ha descubierto un problema en sd-bus en... • http://lists.opensuse.org/opensuse-security-announce/2019-02/msg00070.html • CWE-20: Improper Input Validation CWE-787: Out-of-bounds Write •

CVE-2018-16864 – systemd: stack overflow when calling syslog from a command with long cmdline
https://notcve.org/view.php?id=CVE-2018-16864
09 Jan 2019 — An allocation of memory without limits, that could result in the stack clashing with another memory region, was discovered in systemd-journald when a program with long command line arguments calls syslog. A local attacker may use this flaw to crash systemd-journald or escalate his privileges. Versions through v240 are vulnerable.

CVE-2018-16866 – systemd: out-of-bounds read when parsing a crafted syslog message
https://notcve.org/view.php?id=CVE-2018-16866
09 Jan 2019 — An out of bounds read was discovered in systemd-journald in the way it parses log messages that terminate with a colon ':'. A local attacker can use this flaw to disclose process memory data. Versions from v221 to v239 are vulnerable. Se ha descubierto una lectura fuera de límites en systemd-journald en la forma en la que analiza mensajes de registro que terminan con dos puntos ":".

CVE-2018-18397 – kernel: userfaultfd bypasses tmpfs file permissions
https://notcve.org/view.php?id=CVE-2018-18397
12 Dec 2018 — The userfaultfd implementation in the Linux kernel before 4.19.7 mishandles access control for certain UFFDIO_ ioctl calls, as demonstrated by allowing local users to write data into holes in a tmpfs file (if the user has read-only access to that file, and that file contains holes), related to fs/userfaultfd.c and mm/userfaultfd.c.

CVE-2018-14633 – kernel: stack-based buffer overflow in chap_server_compute_md5() in iscsi target
https://notcve.org/view.php?id=CVE-2018-14633
25 Sep 2018 — A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system... • http://www.securityfocus.com/bid/105388 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
