CVE-2013-7010

Description

Integer signedness errors in FFmpeg's dsputil.c allow out-of-bounds array access via crafted data, leading to denial of service.

AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Integer signedness errors in FFmpeg's dsputil.c allow out-of-bounds array access via crafted data, leading to denial of service.

Vulnerability

Multiple integer signedness errors exist in libavcodec/dsputil.c in FFmpeg before version 2.1. Specifically, in the add_bytes_c and diff_bytes_c functions, the comparison i <= w - sizeof(long) uses sizeof(long) (unsigned) and w (signed int), leading to signedness mismatch that can cause the loop bound to be incorrect, resulting in out-of-bounds array access when processing crafted data. This was fixed in commit [454a11a][4] [3].

Exploitation

An attacker can exploit this vulnerability by providing a specially crafted multimedia file that triggers the vulnerable code path during decoding. No authentication or special privileges are required; the vulnerability can be triggered remotely by convincing a user to process the malicious file with an affected version of FFmpeg.

Impact

Successful exploitation causes an out-of-bounds array access, leading to a denial of service (application crash) and potentially other unspecified impacts such as memory corruption. The impact is limited to the FFmpeg process; no privilege escalation is indicated.

Mitigation

The issue is fixed in FFmpeg version 2.1, released in December 2013, and in commit [454a11a][4]. Users should upgrade to FFmpeg 2.1 or later. No known workarounds exist for unpatched versions.
