SB2019061303 - Ubuntu update for libsndfile

Description

This security bulletin contains information about 13 vulnerabilities.

1) Out-of-bounds read (CVE-ID: CVE-2017-14245)

The vulnerability allows a remote unautheticated attacker to cause DoS condition on the target system.

The weakness exists in the d2alaw_array() function due to improper handling of NAN and INFINITY floating-point values. A remote attacker can send a specially crafted source code, trick the victim into opening it, trigger an out-of-bounds read and cause the service to crash.

2) Out-of-bounds read (CVE-ID: CVE-2017-14246)

The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists in the d2ulaw_array() function due to improper handling of NAN and INFINITY floating-point values. A remote attacker can send a specially crafted input, trick the victim into opening it, trigger an out-of-bounds read and service to crash.

3) Divide by zero (CVE-ID: CVE-2017-14634)

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the double64_init() function due to a divide-by-zero error when processing crafted audio files. A remote attacker can trick the victim into opening a specially crafted audio file, trigger a divide-by-zero condition and cause the service to crash.

4) Out-of-bounds read (CVE-ID: CVE-2017-17456)

The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists in the d2alaw_array() function due to out-of-bounds read. A remote attacker can create a specially crafted source code, trick the victim into opening it, trigger memory corruption and to cause the service to crash.

5) Out-of-bound read (CVE-ID: CVE-2017-17457)

The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists in the d2ulaw_array() function due to out-of-bounds read. A remote attacker send a specially crafted input, trigger memory corruption and cause the service to crash.

6) Out-of-bounds read (CVE-ID: CVE-2017-6892)

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists in the aiff_read_chanmap() function, which is defined in the aiff.c source code file due to improper handling of AIFF files. A remote attacker can create a specially crafted AIFF file, trick the victim into opening it, trigger out-of-bounds read and gain access to potentially sensitive information.

7) Stack-based buffer overflow (CVE-ID: CVE-2018-13139)

The vulnerability allows a remote unauthenticated attacker to cause DoS condition on the target system.

The weakness exists due to stack-based buffer overflow in psf_memset in common.c. A remote attacker can send a specially crafted audio file, trick the victim into opening it, trigger memory corruption and cause the service to crash.

8) NULL pointer dereference (CVE-ID: CVE-2018-19432)

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to NULL pointer dereference in the function sf_write_int in sndfile.c. A remote attacker can trigger NULL pointer dereference and cause the service to crash.

9) Out-of-bounds read (CVE-ID: CVE-2018-19661)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to buffer over-read in the function i2ulaw_array in ulaw.c that will lead to a denial of service. A remote attacker can perform a denial of service attack.

10) Out-of-bounds read (CVE-ID: CVE-2018-19662)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to buffer over-read in the function i2alaw_array in alaw.c that will lead to a denial of service. A remote attacker can perform a denial of service attack.

11) Out-of-bounds read (CVE-ID: CVE-2018-19758)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to heap-based buffer overread condition in the wav_write_headerfunction, as defined in the wav.c source code file. A remote attacker can trick the victim into following a custom link or opening a crafted audio file that submits malicious input, trigger memory corruption and perform a denial of service attack.

12) Division by zero (CVE-ID: CVE-2017-16942)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a divide by zero error in the wav_w64_read_fmt_chunk() function in wav_w64.c file while playing a crafted audio file. A remote attacker can pass a specially crafted file to the affected application, trigger division by zero error and crash the affected application.

13) Out-of-bounds read (CVE-ID: CVE-2019-3832)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in the wav_write_header() function in wav.c file when processing media content. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger out-of-bounds read error and crash the affected application.

Note: this vulnerability is a result of an unresolved issues, described in SB2018112313 (#5).
