AZL-99747 CVE-2026-6554 affecting package libpcap for versions less than 1.10.7-1

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. In particular uncommon use cases a crafted filter program can cause the interpreter to loop infinitely...

CVE-2026-18313

rpcapd can allocate up to 65536 bytes per each RPCAPMSGUPDATEFILTERREQ or RPCAPMSGSTARTCAPREQ message received from the client, but it never frees the memory, so it leaks memory even under normal use. A malicious client can cause the server to leak memory substantially faster...
