CVSS: 6.5EPSS: 0%CPEs: 35EXPL: 0CVE-2020-10690 – kernel: use-after-free in cdev_put() when a PTP device is removed while it's chardev is open
https://notcve.org/view.php?id=CVE-2020-10690
There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed, it can cause an exploitable condition as the process wakes up to terminate and clean all attached files. The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the inode. Se presenta un uso de la memoria previamente liberada en kernel versiones anteriores a 5.5, debido a una condición de carrera entre la liberación de ptp_clock y cdev durante la desasignación de recursos. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10690 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://security.netapp.com/advisory/ntap-20200608-0001 https://usn.ubuntu.com/4419-1 https://access.redhat.com/security/cve/CVE-2020-10690 https://bugzilla.redhat.com/show_bug.cgi?id=1817141 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2020-6831
A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. Podría presentarse un desbordamiento del búfer cuando se analizan y comprueban fragmentos SCTP en WebRTC. Esto podría haber provocado una corrupción en la memoria y un bloqueo potencialmente explotable. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00000.html http://packetstormsecurity.com/files/158480/usrsctp-Stack-Buffer-Overflow.html https://bugzilla.mozilla.org/show_bug.cgi?id=1632241 https://security.gentoo.org/glsa/202005-03 https://security.gentoo.org/glsa/202005-04 https://usn.ubuntu.com/4373-1 https://www.debian.org/security/2020/dsa-4714 https://www.mozilla.org/security/advisories/mfsa2020-16 https://www.mozilla.org/security/advisories/mfsa2020-17 https:&# • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

gss_mech_free in net/sunrpc/auth_gss/gss_mech_switch.c in the rpcsec_gss_krb5 implementation in the Linux kernel through 5.6.10 lacks certain domain_release calls, leading to a memory leak. Note: This was disputed with the assertion that the issue does not grant any access not already available. It is a problem that on unloading a specific kernel module some memory is leaked, but loading kernel modules is a privileged operation. A user could also write a kernel module to consume any amount of memory they like and load that replicating the effect of this bug ** EN DISPUTA ** En la función gss_mech_free en el archivo net/sunrpc/auth_gss/gss_mech_switch.c en la implementación rpcsec_gss_krb5 en el kernel de Linux versiones hasta 5.6.10 carece de ciertas llamadas domain_release, onllevando a una perdida de memoria.
