A stack-based buffer overflow within GNOME gcab through 0.7.4 can be exploited by malicious attackers to cause a crash or, potentially, execute arbitrary code via a crafted .cab file.

Directory traversal vulnerability in the gcab_folder_extract function in libgcab/gcab-folder.c in gcab 0.4 allows remote attackers to write to arbitrary files via crafted path in a CAB file, as demonstrated by "\tmp\moo."
