[Bruce Dubbs]

New minor version.

According to Arch, 5 "security issues" were fixed in this version. I don't see any rush to update it though, but here they are for documentation purposes:

CVE-2019-7665

In elfutils 0.175, a heap-based buffer over-read was discovered in the function elf32_xlatetom in elf32_xlatetom.c in libelf. A crafted ELF input can cause a segmentation fault leading to denial of service (program crash) because ebl_core_note does not reject malformed core file notes.

CVE-2019-7664

In elfutils 0.175, a negative-sized memcpy is attempted in elf_cvt_note in libelf/note_xlate.h because of an incorrect overflow check. Crafted elf input causes a segmentation fault, leading to denial of service (program crash).

CVE-2019-7150

An issue was discovered in elfutils 0.175. A segmentation fault can occur in the function elf64_xlatetom in libelf/elf32_xlatetom.c, due to dwfl_segment_report_module not checking whether the dyn data read from a core file is truncated. A crafted input can cause a program crash, leading to denial-of-service.

CVE-2019-7149

A heap-based buffer over-read was discovered in the function read_srclines in dwarf_getsrclines.c in libdw in elfutils 0.175. A crafted input can cause segmentation faults, leading to denial-of-service.

CVE-2019-7148

An attempted excessive memory allocation was discovered in the function read_long_names in elf_begin.c in libelf in elfutils <= 0.175. Remote attackers could leverage this vulnerability to cause a denial-of-service via crafted elf input, which leads to an out-of-memory exception.

The only thing I see concerning out of that list is the out-of-memory problem. I'm not sure it's worth breaking freeze to update though.

Again, this is put here for documentation purposes.
