CVE-2026-53585

libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid API, allowing to build Git functionality into your application. Prior to 1.8.6 and 1.9.5, gitdeltaapply in src/libgit2/delta.c trusts the attacker-controlled ressz value parsed by hdrsz from...

CVE-2026-53587

libgit2 prior to 1.8.6 and 1.9.5 contains a heap out-of-bounds read in set_data() within src/libgit2/transports/smart_pkt.c. A fixed-size strncmp on an unvalidated smart-protocol pkt-line buffer allows a malicious Git server to cause format_str to advance past the pkt-line boundary, making the su...

Zoo Design Studio: Recursive KCL parsing is vulnerable to denial-of-service

Impact Feeding a KCL program that wraps an expression in deep, unnecessary parentheses triggers the parser’s recursive expression - unnecessarilybracketed - expression path. With enough nesting, the call stack grows until it exceeds the process stack limit, causing a stack overflow...
