Summary

Security update for libpcap

Details

This update for libpcap fixes the following issues:

CVE-2026-0799: the BPF interpreter does not validate values in BPF instructions that load/store a value from/to a scratch memory register and allows for OOB access (bsc#1279782).
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 (bsc#1279595).
CVE-2026-6554: libpcap BPF interpreter treats the offset in the 'ja L' BPF instruction implements looping via backward jumps, but it does not limit the number of loop iterations. Can cause infinite loop (bsc#1279584).
CVE-2026-18238: rpcap client code that processes a RPCAP_MSG_PACKET message received from the server incorrectly validates its headers and allows for an OOB access (bsc#1279783).
CVE-2026-18313: rpcapd allocates up to 65536 bytes per each RPCAP_MSG_UPDATEFILTER_REQ or RPCAP_MSG_STARTCAP_REQ message received from the client and never frees the memory (bsc#1279784).
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 (bsc#1279588).
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 buff (bsc#1279593).
