Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU40938

Risk: High

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2014-9496

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The sd2_parse_rsrc_fork function in sd2.c in libsndfile allows attackers to have unspecified impact via vectors related to a (1) map offset or (2) rsrc marker, which triggers an out-of-bounds read.

Mitigation

Update the affected packages.
media-libs/libsndfile to version: 1.0.26

Vulnerable software versions

Gentoo Linux: All versions

2) Heap-based buffer overflow

EUVDB-ID: #VU33282

Risk: High

CVSSv4.0: 8.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber]

CVE-ID: CVE-2015-7805

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in Heap-based buffer overflow in libsndfile 1.0.25. A remote attacker can use the headindex value in the header in an AIFF file. to trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected packages.
media-libs/libsndfile to version: 1.0.26
