| Vector | AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
elfutils version 0.175
Description
A heap-based buffer over-read was discovered in the
elf32 xlatetom function in libelf. This issue can be triggered by a crafted ELF input, causing a segmentation fault that leads to a denial of service (program crash). The problem arises because ebl core note does not reject malformed core file notes.Recommendations
For elfutils version 0.175, consider disabling the
elf32 xlatetom function as a temporary workaround until a patch is available to prevent potential exploitation. Restrict access to malformed ELF files to minimize the risk of a denial of service. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
