30 March 2022
zlib could be made to crash or run programs if it received specially crafted input.
Releases
Packages
- zlib - Lossless data-compression library
Details
Danilo Ramos discovered that zlib incorrectly handled memory when
performing certain deflating operations. An attacker could use this issue
to cause zlib to crash, resulting in a denial of service, or possibly
execute arbitrary code.
