Stack-based buffer overflow in the file_compress function in minigzip (Modules/zlib) in Python 2.5 allows context-dependent attackers to execute arbitrary code via a long file argument.

python: Generic FAQ wizard moving tool insecure auxiliary /tmp file usage (symlink attack possible)

Tools/faqwiz/move-faqwiz.sh (aka the generic FAQ wizard moving tool) in Python 2.4.5 might allow local users to overwrite arbitrary files via a symlink attack on a tmp$RANDOM.tmp temporary file. NOTE: there may not be common usage scenarios in which tmp$RANDOM.tmp is located in an untrusted directory.
