FreeBSD Security Advisory - FreeBSD-SA-19:08.rack

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.




19

FreeBSD Security Advisory - FreeBSD-SA-19:09.iconv

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.




19

FreeBSD Security Advisory - FreeBSD-SA-19:11.cd_ioctl

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.




19

FreeBSD Security Advisory - FreeBSD-SA-19:10.ufs

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.




19

FreeBSD Security Advisory - FreeBSD-SA-19:12.telnet

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).




19

FreeBSD Security Advisory - FreeBSD-SA-19:14.freebsd32

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.




19

FreeBSD Security Advisory - FreeBSD-SA-19:15.mqueuefs

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.




19

FreeBSD Security Advisory - FreeBSD-SA-19:16.bhyve

FreeBSD Security Advisory - The pci_xhci_device_doorbell() function does not validate the 'epid' and 'streamid' provided by the guest, leading to an out-of-bounds read. A misbehaving bhyve guest could crash the system or access memory that it should not be able to.




19

FreeBSD Security Advisory - FreeBSD-SA-19:17.fd

FreeBSD Security Advisory - If a process attempts to transmit rights over a UNIX-domain socket and an error causes the attempt to fail, references acquired on the rights are not released and are leaked. This bug can be used to cause the reference counter to wrap around and free the corresponding file structure. A local user can exploit the bug to gain root privileges or escape from a jail.




19

FreeBSD Security Advisory - FreeBSD-SA-19:18.bzip2

FreeBSD Security Advisory - The decompressor used in bzip2 contains a bug which can lead to an out-of-bounds write when processing a specially crafted bzip2(1) file. bzip2recover contains a heap use-after-free bug which can be triggered when processing a specially crafted bzip2(1) file. An attacker who can cause maliciously crafted input to be processed may trigger either of these bugs. The bzip2recover bug may cause a crash, permitting a denial-of-service. The bzip2 decompressor bug could potentially be exploited to execute arbitrary code. Note that some utilities, including the tar(1) archiver and the bspatch(1) binary patching utility (used in portsnap(8) and freebsd-update(8)) decompress bzip2(1)-compressed data internally; system administrators should assume that their systems will at some point decompress bzip2(1)-compressed data even if they never explicitly invoke the bunzip2(1) utility.




19

FreeBSD Security Advisory - FreeBSD-SA-19:19.mldv2

FreeBSD Security Advisory - The ICMPv6 input path incorrectly handles cases where an MLDv2 listener query packet is internally fragmented across multiple mbufs. A remote attacker may be able to cause an out-of-bounds read or write that may cause the kernel to attempt to access an unmapped page and subsequently panic.




19

FreeBSD Security Advisory - FreeBSD-SA-19:20.bsnmp

FreeBSD Security Advisory - A function extracting the length from type-length-value encoding is not properly validating the submitted length. A remote user could cause, for example, an out-of-bounds read, decoding of unrelated data, or trigger a crash of the software such as bsnmpd resulting in a denial of service.




19

FreeBSD Security Advisory - FreeBSD-SA-19:21.bhyve

FreeBSD Security Advisory - The e1000 network adapters permit a variety of modifications to an Ethernet packet when it is being transmitted. These include the insertion of IP and TCP checksums, insertion of an Ethernet VLAN header, and TCP segmentation offload ("TSO"). The e1000 device model uses an on-stack buffer to generate the modified packet header when simulating these modifications on transmitted packets. When TCP segmentation offload is requested for a transmitted packet, the e1000 device model used a guest-provided value to determine the size of the on-stack buffer without validation. The subsequent header generation could overflow an incorrectly sized buffer or indirect a pointer composed of stack garbage. A misbehaving bhyve guest could overwrite memory in the bhyve process on the host.




19

FreeBSD Security Advisory - FreeBSD-SA-19:22.mbuf

FreeBSD Security Advisory - Due do a missing check in the code of m_pulldown(9) data returned may not be contiguous as requested by the caller. Extra checks in the IPv6 code catch the error condition and trigger a kernel panic leading to a remote DoS (denial-of-service) attack with certain Ethernet interfaces. At this point it is unknown if any other than the IPv6 code paths can trigger a similar condition.




19

FreeBSD Security Advisory - FreeBSD-SA-19:23.midi

FreeBSD Security Advisory - The kernel driver for /dev/midistat implements a handler for read(2). This handler is not thread-safe, and a multi-threaded program can exploit races in the handler to cause it to copy out kernel memory outside the boundaries of midistat's data buffer. The races allow a program to read kernel memory within a 4GB window centered at midistat's data buffer. The buffer is allocated each time the device is opened, so an attacker is not limited to a static 4GB region of memory. On 32-bit platforms, an attempt to trigger the race may cause a page fault in kernel mode, leading to a panic.




19

FreeBSD Security Advisory - FreeBSD-SA-19:24.mqueuefs

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.
