HighMetricsAV:N/AC:M/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions
Libelfin version 0.3
Description
The issue is related to the dwarf::cursor::skip form function in Libelfin, which can be exploited by attackers to cause a denial of service (DOS) through a segmentation fault. This can be achieved by using a crafted ELF file. The vulnerability is associated with insufficient neutralization of special elements in the request, allowing a remote attacker to disrupt service.
Recommendations
For Libelfin version 0.3, consider disabling the
dwarf::cursor::skip form function as a temporary workaround until a patch is available. Restrict access to the dwarf::cursor::skip form function to minimize the risk of exploitation. Avoid using crafted ELF files that could trigger the denial of service. Found an issue in the description? Have something to add? Feel free to write us 👾
