GHSA-6CCX-9C9F-327W gRPC Erlang package has unbounded gzip decompression (decompression bomb)

Summary An unauthenticated remote peer can crash any gRPC server built on this library by sending a small gzip-compressed frame that decompresses to gigabytes, exhausting the BEAM node's heap and triggering an OOM kill denial of service. Introduced in...

The vulnerability of the copy_data_into_buffer() function in the fs/btrfs/zlib.c file of the btrfs file system in the Linux kernel allows a attacker to cause a service failure.

The vulnerability of the copydataintobuffer function in the fs/btrfs/zlib.c file of the btrfs file system in the Linux kernel allows for the copying of buffers without checking the size of the input data a classic buffer overflow attack. Exploiting this vulnerability can enable an attacker to cau...

AZL-105345 CVE-2026-76844 affecting package zlib 1.3.2-1

zlib 1.2.11 through 1.3.2 contains a heap buffer overflow: after an underlying write fails, gzwrite returns without resetting strm.nextin, leaving it pointed at the caller's buffer. A later gz write call then derives a position from the stale pointer and writes past a heap allocation; any write...
