libxpm: Multiple issues (5.0)
Last modified: 2023-06-21 12:33:52 CEST
New Debian libxpm 1:3.5.12-1+deb10u1 fixes: This update addresses the following issues: 1:3.5.12-1+deb10u1 (Mon, 19 Jun 2023 20:27:53 +0000) * Non-maintainer upload by the LTS Security Team. * Switch to dpkg-source 3.0 (quilt) format * Fix CVE-2022-4883: When processing files with .Z or .gz extensions, the library calls external programs to compress and uncompress files, relying on the PATH environment variable to find these programs, which could allow a malicious user to execute other programs by manipulating the PATH environment variable. * Fix CVE-2022-44617: When processing a file with width of 0 and a very large height, some parser functions will be called repeatedly and can lead to an infinite loop, resulting in a Denial of Service in the application linked to the library. * Fix CVE-2022-46285: when parsing a file with a comment not closed an end-of-file condition will not be detected, leading to an infinite loop and resulting in a Denial of Service in the application linked to the library.
