Gnu: Security Vulnerabilities
GNU assembler in GNU Binutils 2.28 is vulnerable to a global buffer overflow (of size 1) while attempting to unget an EOF character from the input stream, potentially leading to a program crash.

The find_nearest_line function in addr2line in GNU Binutils 2.28 does not handle the case where the main file name and the directory name are both empty, triggering a NULL pointer dereference and an invalid write, and leading to a program crash.

The pe_ILF_object_p function in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.28, is vulnerable to a heap-based buffer over-read of size 4049 because it uses the strlen function instead of strnlen, leading to program crashes in several utilities such as addr2line, size, and strings. It could lead to information disclosure as well.

GNU linker (ld) in GNU Binutils 2.28 is vulnerable to a heap-based buffer overflow while processing a bogus input script, leading to a program crash. This relates to lack of '\0' termination of a name field in ldlex.l.

Integer overflow in the _IO_wstr_overflow function in libio/wstrops.c in the GNU C Library (aka glibc or libc6) before 2.22 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors related to computing a size in bytes, which triggers a heap-based buffer overflow.
