BIT-LIBPYTHON-2026-6100 Use-after-free in lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile after re-use under memory pressure

Use-after-free UAF was possible in the lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile when a memory allocation fails with a MemoryError and the decompression instance is re-used. This scenario can be triggered if the process is under memory pressure. The fix cleans up the dangling...

github.com/sigstore/rekor: Rekor: Denial of Service due to unbounded gzip decompression in Alpine APK parsing

A flaw was found in Rekor. The Package.Unmarshal function, which processes Alpine Package Keep APK files, decompresses gzip streams without limiting the total decompressed size. A remote attacker can exploit this by crafting a malicious APK file with a high compression ratio, causing the server t...

SUSE CVE-2026-41991

GNU gzip contains a vulnerability in the gzexe utility related to insecure temporary file handling. When the mktemp utility is not available in the user's PATH, gzexe falls back to constructing a temporary file path based solely on the process ID PID. This predictable filename is created without...

SUSE CVE-2026-41992

GNU gzip contains a global buffer overflow vulnerability in the LZH decompression logic caused by improper reuse of shared global state between different decompression formats within a single execution. GNU gzip maintains a global array that is shared across the LZ77, LZW, and LZH decompression...
