7.1
High
| Vector | AV:N/AC:M/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
libarchive versions 3.0.2 and later
Description
The issue is related to an out-of-bounds read in the libarchive library, specifically in the 7zip decompression functionality. This can be exploited by a remote attacker using a specially crafted 7zip file, potentially leading to a denial of service. The vulnerable function is located in archive read support format 7zip.c, specifically in the
header bytes() function.Recommendations
For libarchive versions 3.0.2 and later, consider avoiding the use of the 7zip decompression feature until a patch is available. As a temporary workaround, restrict access to specially crafted 7zip files to minimize the risk of exploitation.
