According to the versions of the libvpx package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
A denial of service vulnerability in libvpx in Mediaserver could enable a remote attacker to use a specially crafted file to cause a device hang or reboot. This issue is rated as High due to the possibility of remote denial of service. Product:
Android. Versions: 4.4.4, 5.0.2, 5.1.1, 6.0, 6.0.1, 7.0, 7.1. Android ID: A-30436808.(CVE-2017-0393)
In libvpx, there is a possible information disclosure due to improper input validation. This could lead to remote information disclosure with no additional execution privileges needed. User interaction is needed for exploitation. Product: AndroidVersions:
Android-10Android ID: A-80479354(CVE-2019-9433)
libvpx contains an out-of-bounds read flaw in the vp8_mv_bit_cost() and mv_err_cost() functions in vp8/encoder/mcomp.c that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to crash a process linked against the library or potentially disclose sensitive memory contents.(CVE-2018-9349)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
