Use of Default Password vulnerability in ABB RCCMD on Windows, Linux, MacOS allows Try Common or Default Usernames and Passwords.This issue affects RCCMD: before 4.40 230207.

In the Linux kernel through 6.2.8, net/bluetooth/hci_sync.c allows out-of-bounds access because amp_init1[] and amp_init2[] are supposed to have an intentionally invalid element, but do not.

A NULL pointer dereference was found in io_file_bitmap_get in io_uring/filetable.c in the io_uring sub-component in the Linux Kernel. When fixed files are unregistered, some context information (file_alloc_{start,end} and alloc_hint) is not cleared. A subsequent request that has auto index selection enabled via IORING_FILE_INDEX_ALLOC can cause a NULL pointer dereference. An unprivileged user can use the flaw to cause a system crash.

A flaw was found in rizin. The create_section_from_phdr function allocates space for ELF section data by processing the headers. Crafted values in the headers can cause out of bounds reads, which can lead to memory corruption and possibly code execution through the binary object's callback function.

A heap-based buffer overflow was discovered in upx, during the generic pointer 'p' points to an inaccessible address in func get_le32(). The problem is essentially caused in PackLinuxElf32::elf_lookup() at p_lx_elf.cpp:5382.

A heap-based buffer overflow was discovered in upx, during the variable 'bucket' points to an inaccessible address. The issue is being triggered in the function PackLinuxElf64::invert_pt_dynamic at p_lx_elf.cpp:5239.
