Qualys has discovered that OpenBSD suffers from multiple authentication bypass and local privilege escalation vulnerabilities.

Qualys discovered a local privilege escalation in OpenBSD's dynamic loader (ld.so). This vulnerability is exploitable in the default installation (via the set-user-ID executable chpass or passwd) and yields full root privileges. They developed a simple proof of concept and successfully tested it against OpenBSD 6.6 (the current release), 6.5, 6.2, and 6.1, on both amd64 and i386; other releases and architectures are probably also exploitable.

Secunia Security Advisory - A vulnerability has been reported in CuteSoft Cute Editor for ASP.NET, which can be exploited by malicious people to conduct cross-site scripting attacks.

Secunia Security Advisory - A vulnerability has been reported in MirBSD Korn Shell, which can be exploited by malicious, local users to gain escalated privileges.

FreeBSD Security Advisory - Crypto-NAK packets can be used to cause ntpd(8) to accept time from an unauthenticated ephemeral symmetric peer by bypassing the authentication required to mobilize peer associations. FreeBSD 9.3 and 10.1 are not affected. Various other issues have also been addressed.

Debian Linux Security Advisory 3417-1 - Tibor Jager, Jorg Schwenk, and Juraj Somorovsky, from Horst Gortz Institute for IT Security, published a paper in ESORICS 2015 where they describe an invalid curve attack in Bouncy Castle Crypto, a Java library for cryptography. An attacker is able to recover private Elliptic Curve keys from different applications, for example, TLS servers.

Red Hat Security Advisory 2020-1975-01 - Git is a distributed revision control system with a decentralized architecture. As opposed to centralized version control systems with a client-server model, Git ensures that each working copy of a Git repository is an exact copy with complete revision history. This not only allows the user to work on and contribute to projects without the need to have permission to push the changes to their official repositories, but also makes it possible for the user to work with no network connection. Issues addressed include a password leak vulnerability.

FreeBSD Security Advisory - While processing acknowledgements, the RACK code uses several linked lists to maintain state entries. A malicious attacker can cause the lists to grow unbounded. This can cause an expensive list traversal on every packet being processed, leading to resource exhaustion and a denial of service. An attacker with the ability to send specially crafted TCP traffic to a victim system can degrade network performance and/or consume excessive CPU by exploiting the inefficiency of traversing the potentially very large RACK linked lists with relatively small bandwidth cost.

FreeBSD Security Advisory - With certain inputs, iconv may write beyond the end of the output buffer. Depending on the way in which iconv is used, an attacker may be able to create a denial of service, provoke incorrect program behavior, or induce a remote code execution. iconv is a libc library function and the nature of possible attacks will depend on the way in which iconv is used by applications or daemons.

FreeBSD Security Advisory - To implement one particular ioctl, the Linux emulation code used a special interface present in the cd(4) driver which allows it to copy subchannel information directly to a kernel address. This interface was erroneously made accessible to userland, allowing users with read access to a cd(4) device to arbitrarily overwrite kernel memory when some media is present in the device. A user in the operator group can make use of this interface to gain root privileges on a system with a cd(4) device when some media is present in the device.

FreeBSD Security Advisory - A bug causes up to three bytes of kernel stack memory to be written to disk as uninitialized directory entry padding. This data can be viewed by any user with read access to the directory. Additionally, a malicious user with write access to a directory can cause up to 254 bytes of kernel stack memory to be exposed. Some amount of the kernel stack is disclosed and written out to the filesystem.

FreeBSD Security Advisory - Insufficient validation of environment variables in the telnet client supplied in FreeBSD can lead to stack-based buffer overflows. A stack-based overflow is present in the handling of environment variables when connecting via the telnet client to remote telnet servers. This issue only affects the telnet client. Inbound telnet sessions to telnetd(8) are not affected by this issue. These buffer overflows may be triggered when connecting to a malicious server, or by an active attacker in the network path between the client and server. Specially crafted TELNET command sequences may cause the execution of arbitrary code with the privileges of the user invoking telnet(1).

FreeBSD Security Advisory - Due to insufficient initialization of memory copied to userland in the components listed above small amounts of kernel memory may be disclosed to userland processes. A user who can invoke 32-bit FreeBSD ioctls may be able to read the contents of small portions of kernel memory. Such memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way; for example, a terminal buffer might include a user-entered password.

FreeBSD Security Advisory - System calls operating on file descriptors obtain a reference to relevant struct file which due to a programming error was not always put back, which in turn could be used to overflow the counter of affected struct file. A local user can use this flaw to obtain access to files, directories, sockets etc. opened by processes owned by other users. If obtained struct file represents a directory from outside of user's jail, it can be used to access files outside of the jail. If the user in question is a jailed root they can obtain root privileges on the host system.
