CVE-2019-17455
https://notcve.org/view.php?id=CVE-2019-17455
Libntlm through 1.5 relies on a fixed buffer size for tSmbNtlmAuthRequest, tSmbNtlmAuthChallenge, and tSmbNtlmAuthResponse read and write operations, as demonstrated by a stack-based buffer over-read in buildSmbNtlmAuthRequest in smbutil.c for a crafted NTLM request. Libntlm versiones hasta 1.5, se basa en un tamaño de búfer fijo para operaciones de lectura y escritura de las funciones tSmbNtlmAuthRequest, tSmbNtlmAuthChallenge y tSmbNtlmAuthResponse, como es demostrado por una lectura excesiva de búfer en la región heap de la memoria en la función buildSmbNtlmAuthRequest en el archivo smbutil.c para una petición NTLM especialmente diseñada. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00029.html http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00032.html https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=942145 https://gitlab.com/jas/libntlm/issues/2 https://lists.debian.org/debian-lts-announce/2020/05/msg00010.html https://lists.debian.org/debian-lts-announce/2021/11/msg00026.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3BVFO3OVJPMSGIXBKNOCVOJZ3UTGZQF5 • CWE-125: Out-of-bounds Read •
CVE-2019-17133 – kernel: buffer overflow in cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c
https://notcve.org/view.php?id=CVE-2019-17133
In the Linux kernel through 5.3.2, cfg80211_mgd_wext_giwessid in net/wireless/wext-sme.c does not reject a long SSID IE, leading to a Buffer Overflow. En el kernel de Linux versiones hasta 5.3.2, la función cfg80211_mgd_wext_giwessid en el archivo net/wireless/wext-sme.c no rechaza un SSID IE largo, conllevando a un Desbordamiento de Búfer. A vulnerability was found in the Linux kernel's generic WiFi ESSID handling implementation. The flaw allows a system to join a wireless network where the ESSID is longer than the maximum length of 32 characters, which can cause the system to crash or execute code. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00010.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0374 https://access.redhat.com/errata/RHSA-2020:0375 https://access.redhat.com/errata/RHSA-2020:0543 https://access.redhat.com/errata/RHSA-2020:0592 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
