CVE-2015-7830
Status: ModifiedMedium (4.3)—
The pcapng_read_if_descr_block function in wiretap/pcapng.c in the pcapng parser in Wireshark 1.12.x before 1.12.8 uses too many levels of pointer indirection, which allows remote attackers to cause a denial of service (incorrect free and application crash) via a crafted packet that triggers interface-filter copying.
CVSS
- Version: 2.0
- Vector: AV:N/AC:M/Au:N/C:N/I:N/A:P
- Base score: 4.3
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 3.04%
- Percentile among all scored CVEs: 87
- Score date: 10/7/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
