  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

    description Multiple vulnerabilities have been found in libav : CVE-2015-8365 The smka_decode_frame function in libavcodec/smacker.c does not verify that the data size is consistent with the number of channels, which allows remote attackers to cause a denial of service (out-of-bounds array access) or possibly have unspecified other impact via crafted Smacker data. CVE-2017-7208 The decode_residual function in libavcodec allows remote attackers to cause a denial of service (buffer over-read) or obtain sensitive information from process memory via a crafted h264 video file. CVE-2017-7862 The decode_frame function in libavcodec/pictordec.c is vulnerable to an out-of-bounds write caused by a heap-based buffer overflow. CVE-2017-9992 The decode_dds1 function in libavcodec/dfa.c allows remote attackers to cause a denial of service (Heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file. For Debian 7 'Wheezy', these problems have been fixed in version 6:0.8.21-0+deb7u1. We recommend that you upgrade your libav packages. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
