An issue was discovered in HAProxy before 1.8.8. The incoming H2 frame length was checked against the max_frame_size setting instead of being checked against the bufsize. The max_frame_size only applies to outgoing traffic and not to incoming, so if a large enough frame size is advertised in the SETTINGS frame, a wrapped frame will be defragmented into a temporary allocated buffer where the second fragment may overflow the heap by up to 16 kB. It is very unlikely that this can be exploited for code execution given that buffers are very short lived and their addresses not realistically predictable in production, but the likelihood of an immediate crash is absolutely certain.

A vulnerability has been identified in Capital Embedded AR Classic 431-422 (All versions), Capital Embedded AR Classic R20-11 (All versions < V2303). The DHCP client application does not validate the length of the Domain Name Server IP option(s) (0x06) when processing DHCP ACK packets. This may lead to Denial-of-Service conditions. (FSMD-2021-0011)

There was a Memory Corruption issue discovered in multiple models of Axis IP Cameras which causes a denial of service (crash). The crash arises from code inside libdbus-send.so shared object or similar.

The FileInfo plugin before 2.22 for Ghisler Total Commander allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via (1) a large Size value in the Archive Member Header of a COFF Archive Library file, (2) a large Number Of Symbols value in the 1st Linker Member of a COFF Archive Library file, (3) a large Resource Table Count value in the LE Header of a Linear Executable file, or (4) a large value in a certain Object field in a Resource Table Entry in a Linear Executable file.

In the standard library in Rust before 1.2.0, BinaryHeap is not panic-safe. The binary heap is left in an inconsistent state when the comparison of generic elements inside sift_up or sift_down_range panics. This bug leads to a drop of zeroed memory as an arbitrary type, which can result in a memory safety violation.

The osi_print_cksum function in print-isoclns.c in the ethernet printer in tcpdump before 4.7.2 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted (1) length, (2) offset, or (3) base pointer checksum value.

The rpki_rtr_pdu_print function in print-rpki-rtr.c in the TCP printer in tcpdump before 4.7.2 allows remote attackers to cause a denial of service (out-of-bounds read or write and crash) via a crafted header length in an RPKI-RTR Protocol Data Unit (PDU).

The prefix variable in the get_or_define_ns function in Lasso before commit 6d854cef4211cdcdbc7446c978f23ab859847cdd allows remote attackers to cause a denial of service (uninitialized memory access and application crash) via unspecified vectors.

There is a heap-based buffer overflow in the function hpel_motion in mpegvideo_motion.c in libav 12.1. A crafted input can lead to a remote denial of service attack.

In curl before 7.54.1 on Windows and DOS, libcurl's default protocol function, which is the logic that allows an application to set which protocol libcurl should attempt to use when given a URL without a scheme part, had a flaw that could lead to it overwriting a heap based memory buffer with seven bytes. If the default protocol is specified to be FILE or a file: URL lacks two slashes, the given "URL" starts with a drive letter, and libcurl is built for Windows or DOS, then libcurl would copy the path 7 bytes off, so that the end of the given path would write beyond the malloc buffer (7 bytes being the length in bytes of the ascii string "file://").

The grub_ext2_read_block function in fs/ext2.c in GNU GRUB before 2013-11-12, as used in shlr/grub/fs/ext2.c in radare2 1.5.0, allows remote attackers to cause a denial of service (excessive stack use and application crash) via a crafted binary file, related to use of a variable-size stack array.

In Wireshark 2.2.0 to 2.2.6 and 2.0.0 to 2.0.12, the DHCP dissector could read past the end of a buffer. This was addressed in epan/dissectors/packet-bootp.c by extracting the Vendor Class Identifier more carefully.

A vulnerability in the web portal of the Cisco Prime Collaboration Provisioning Tool could allow an unauthenticated, remote attacker to create a denial of service (DoS) condition for individual users. The vulnerability is due to weak login controls. An attacker could exploit this vulnerability by using a brute-force attack (Repeated Bad Login Attempts). A successful exploit could allow the attacker to restrict user access. Manual administrative intervention is required to restore access. Cisco Bug IDs: CSCvd07264.

Schneider Electric's ClearSCADA versions released prior to August 2017 are susceptible to a memory allocation vulnerability, whereby malformed requests can be sent to ClearSCADA client applications to cause unexpected behavior. Client applications affected include ViewX and the Server Icon.

In Irssi before 1.0.3, when receiving certain incorrectly quoted DCC files, it tries to find the terminating quote one byte before the allocated memory. Thus, remote attackers might be able to cause a crash.

A vulnerability in the forwarding information base (FIB) code of Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause inconsistency between the routing information base (RIB) and the FIB, resulting in a denial of service (DoS) condition. The vulnerability is due to incorrect processing of extremely long routing updates. An attacker could exploit this vulnerability by sending a large routing update. A successful exploit could allow the attacker to trigger inconsistency between the FIB and the RIB, resulting in a DoS condition. Cisco Bug IDs: CSCus84718.

In the standard library in Rust before 1.51.0, the Zip implementation calls __iterator_get_unchecked() for the same index more than once when nested. This bug can lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait.

analyzer/protocol/dnp3/DNP3.cc in Bro before 2.3.2 does not properly handle zero values of a packet length, which allows remote attackers to cause a denial of service (buffer overflow or buffer over-read if NDEBUG; otherwise assertion failure) via a crafted DNP3 packet.

analyzer/protocol/dnp3/DNP3.cc in Bro before 2.3.2 does not reject certain non-zero values of a packet length, which allows remote attackers to cause a denial of service (buffer overflow or buffer over-read) via a crafted DNP3 packet.

An issue was discovered in sthttpd through 2.27.1. On systems where the strcpy function is implemented with memcpy, the de_dotdot function may cause a Denial-of-Service (daemon crash) due to overlapping memory ranges being passed to memcpy. This can triggered with an HTTP GET request for a crafted filename. NOTE: this is similar to CVE-2017-10671, but occurs in a different part of the de_dotdot function.
