High
| Vector | AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions:
sharutils version 4.15.2
Description:
The issue is related to a Buffer Overflow in the
unshar command, specifically in the unshar.c file at line 75, within the looks like c code function. This occurs due to a failure in checking the buffer containing the input line, which could lead to code execution. The attack appears to be exploitable if a victim runs the unshar command on a specially crafted file.Recommendations:
For sharutils version 4.15.2, consider avoiding the use of the
unshar command until a patch is available, or apply any available patches to resolve the Buffer Overflow issue in the looks like c code function. As a temporary workaround, restrict the execution of specially crafted files with the unshar command to minimize the risk of exploitation.Fix
