[SECURITY] Fedora 45 Update: libpcap-1.10.7-1.fc45
Libpcap provides a portable framework for low-level network monitoring. Libpcap can provide network statistics collection, security monitoring and network debugging. Since almost every system vendor provides a different interface for packet capture, the libpcap authors created this...
Fedora 45 : libpcap (2026-c3fb234b87)
The remote Fedora 45 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-c3fb234b87 advisory. New version 10.7.1 Fix for CVE-2026-0799, CVE-2026-6244, CVE-2026-6554, CVE-2026-18238, CVE-2026-18313, CVE-2026-31911, CVE-2026-31912 Tenable has...
OPENSUSE-SU-2026:11744-1 libpcap-devel-1.10.7-1.1 on GA media
These are all security issues fixed in the libpcap-devel-1.10.7-1.1 package on the GA media of openSUSE Tumbleweed...
CVE-2026-0799
A flaw was found in libpcap. The Berkeley Packet Filter BPF interpreter in libpcap does not properly validate register indexes in BPF instructions. A local attacker could craft a malicious filter program to trigger an out-of-bounds read and write vulnerability. This could allow the attacker to re...
CVE-2026-31911
A flaw was found in libpcap. A local attacker could provide a crafted filter program containing an invalid Berkeley Packet Filter BPF opcode. This could cause the operating system OS process using libpcap to terminate, leading to a Denial of Service DoS...
CVE-2026-18313
A flaw was found in libpcap, specifically within the rpcapd daemon. This vulnerability allows a remote attacker to cause a denial of service DoS by sending specially crafted RPCAPMSGUPDATEFILTERREQ or RPCAPMSGSTARTCAPREQ messages. The rpcapd daemon allocates memory for these messages but fails to...
CVE-2026-18238
A flaw was found in libpcap. The rpcap client code, which processes RPCAPMSGPACKET messages from a server, incorrectly validates its headers. A malicious server could exploit this vulnerability by sending a specially crafted message, causing the client to read up to 20 bytes of memory beyond its...
CVE-2026-6244
A flaw was found in libpcap. The Berkeley Packet Filter BPF interpreter's 'div k' and 'mod k' instructions do not validate if the immediate value 'k' is zero. A local attacker with low privileges could exploit this by providing a specially crafted filter program, leading to a division-by-zero...
CVE-2026-6554
A flaw was found in libpcap. The Berkeley Packet Filter BPF interpreter incorrectly handles offsets in 'ja L' instructions, allowing backward jumps without limiting loop iterations. A local attacker could provide a specially crafted filter program, leading to an infinite loop and causing a Denial...
SUSE CVE-2026-0799
In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not validate the value. In particular uncommon use cases a crafted filter program can cause the interpreter to tr...
SUSE CVE-2026-6244
libpcap BPF interpreter for the 'div k' and 'mod k' ALU instructions does not check whether the immediate value is zero. In particular uncommon use cases a crafted filter program can cause a division by zero...
SUSE CVE-2026-6554
libpcap BPF interpreter treats the offset in the 'ja L' BPF instruction as a signed integer to implement looping via backward jumps, but it does not limit the number of loop iterations. A crafted filter program or the 'protochain' primitive used on a crafted network packet can cause the interpret...
SUSE CVE-2026-31911
libpcap BPF interpreter calls abort if it encounters a BPF instruction that has an invalid opcode. In particular uncommon use cases a crafted filter program can terminate the OS process...
SUSE CVE-2026-31912
libpcap BPF interpreter detects neither reaching the end of the filter program buffer due to lack of a return instruction nor executing a jump instruction with an offset that translates to a pointer outside of the buffer. In particular uncommon use cases a crafted filter program can cause the...
