None · Zziplib · CVE-2018-6381
**Name of the Vulnerable Software and Affected Versions**
ZZIPlib versions 0.13.56 through 0.13.67
**Description**
The issue is related to invalid memory access in the `zzip disk fread` function, causing a segmentation fault. This occurs because the size variable is not validated against the amount of file->stored data. Additionally, there is a buffer overflow vulnerability in the `zzip mem entry new` function, which can be exploited by a remote attacker to cause a denial of service.
**Recommendations**
For ZZIPlib versions 0.13.56 through 0.13.67, consider disabling the `zzip disk fread` function and the `zzip mem entry new` function until a patch is available. Restrict access to the `zzip/mmapped.c` and `zzip/memdisk.c` files to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
