CVSS: 5.5EPSS: 0%CPEs: 11EXPL: 1CVE-2018-18310 – elfutils: invalid memory address dereference was discovered in dwfl_segment_report_module.c in libdwfl
https://notcve.org/view.php?id=CVE-2018-18310
An invalid memory address dereference was discovered in dwfl_segment_report_module.c in libdwfl in elfutils through v0.174. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by consider_notes. Se ha descubierto una desreferencia de dirección de memoria inválida en dwfl_segment_report_module.c en libdwfl en elfutils 0.4.8 hasta la versión v0.174. La vulnerabilidad permite que los atacantes provoquen una denegación de servicio (cierre inesperado de la aplicación) mediante un archivo ELF manipulado, tal y como queda demostrado con consider_notes. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00052.html https://access.redhat.com/errata/RHSA-2019:2197 https://lists.debian.org/debian-lts-announce/2019/02/msg00036.html https://lists.debian.org/debian-lts-announce/2021/10/msg00030.html https://sourceware.org/bugzilla/show_bug.cgi?id=23752 https://sourceware.org/ml/elfutils-devel/2018-q4/msg00022.html https://usn.ubuntu.com/4012-1 https://access.redhat.com/security/cve/CVE-2018-18310 https://bugzilla.redh • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

Qemu has a Buffer Overflow in pcnet_receive in hw/net/pcnet.c because an incorrect integer data type is used. Qemu tiene un desbordamiento de búfer en pcnet_receive en hw/net/pcnet.c debido a que se emplea un tipo de datos de enteros incorrecto. An integer overflow issue was found in the AMD PC-Net II NIC emulation in QEMU. It could occur while receiving packets, if the size value was greater than INT_MAX. Such overflow would lead to stack buffer overflow issue. • http://www.openwall.com/lists/oss-security/2018/10/08/1 https://access.redhat.com/errata/RHSA-2019:2892 https://access.redhat.com/security/cve/cve-2018-17962 https://linux.oracle.com/cve/CVE-2018-17962.html https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2018-09/msg03268.html https://usn.ubuntu.com/3826-1 https://www.debian.org/security/2018/dsa-4338 https://www.suse.com/security/cve/CVE-2 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •
