| Vetor | AV:N/AC:M/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions:
ZZIPlib version 0.13.67
Description:
The issue is related to the zzip disk findfirst function in the zzip/mmapped.c file, which can cause a bus error due to the loading of a misaligned address. This can be exploited by remote attackers to cause a denial of service using a crafted zip file. The vulnerability is also associated with an incorrect buffer size calculation in the zzip disk findfirst function of the ZZIPlib archiving library.
Recommendations:
For ZZIPlib version 0.13.67, consider avoiding the use of the
zzip disk findfirst function until a patch is available. As a temporary workaround, restrict the handling of zip files from untrusted sources to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
