ASA-201910-6: unbound: denial of service

Arch Linux Security Advisory ASA-201910-6
=========================================

Severity: High
Date : 2019-10-11
CVE-ID : CVE-2019-16866
Package : unbound
Type : denial of service
Remote : Yes
Link : https://security.archlinux.org/AVG-1042

Summary
=======

The package unbound before version 1.9.4-1 is vulnerable to denial of
service.

Resolution
==========

Upgrade to 1.9.4-1.

# pacman -Syu "unbound>=1.9.4-1"

The problem has been fixed upstream in version 1.9.4.

Workaround
==========

None.

Description
===========

Due to an error in parsing NOTIFY queries, it is possible for Unbound
from 1.7.1 up to and including 1.9.3 to continue processing malformed
queries and may ultimately result in a pointer dereference in
uninitialized memory. This results in a crash of the Unbound daemon.

Impact
======

A remote attacker might be able to crash the Unbound server via crafted
NOTIFY queries.

Description
===========

- CVE-2019-7572 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a buffer over-read in IMA_ADPCM_nibble in audio/SDL_wave.c.

- CVE-2019-7573 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in InitMS_ADPCM in audio/SDL_wave.c
(inside the wNumCoef loop).

- CVE-2019-7574 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in IMA_ADPCM_decode in audio/SDL_wave.c.

- CVE-2019-7575 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer overflow in MS_ADPCM_decode in audio/SDL_wave.c.

- CVE-2019-7576 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in InitMS_ADPCM in audio/SDL_wave.c
(outside the wNumCoef loop).

- CVE-2019-7577 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a buffer over-read in SDL_LoadWAV_RW in audio/SDL_wave.c.

- CVE-2019-7578 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in InitIMA_ADPCM in audio/SDL_wave.c.

- CVE-2019-7635 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in Blit1to4 in video/SDL_blit_1.c.

- CVE-2019-7636 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in SDL_GetRGB in video/SDL_pixels.c.

- CVE-2019-7637 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer overflow in SDL_FillRect in video/SDL_surface.c.

- CVE-2019-7638 (arbitrary code execution)

SDL (Simple DirectMedia Layer) through 1.2.15 and 2.x through 2.0.9 has
a heap-based buffer over-read in Map1toN in video/SDL_pixels.c.

- CVE-2019-13616 (arbitrary code execution)

A heap-based buffer overflow was discovered in SDL in the
SDL_BlitCopy() function, that was called while copying an existing
surface into a new optimized one, due to lack of validation while
loading a BMP image in the SDL_LoadBMP_RW() function. An application
that uses SDL to parse untrusted input files may be vulnerable to this
flaw, which could allow an attacker to make the application crash or
possibly execute code.

Impact
======

An attacker can execute arbitrary code on the affected host via a
crafted audio, image or video file.
