We apologize for the inconvenience.

Original advisory details:

Avi Halachmi discovered that Git incorrectly managed file modification constraints with Gitk. An attacker could possibly use this issue to create or write to arbitrary files on the system. (CVE-2025-27613)

Avi Halachmi discovered that Git incorrectly handled arguments when invoking the Gitk utility. If a user were tricked into cloning a malicious Git repository, an attacker could possibly use this issue to run arbitrary commands. This issue only affected Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04. (CVE-2025-27614)

Johannes Sixt discovered that Git incorrectly managed file modification constraints with Git GUI. If a user were tricked into editing a file in a malicious Git repository, an attacker could possibly use this issue to create or write to arbitrary files on the system. (CVE-2025-46835)

David Leadbeater discovered that Git incorrectly stripped CRLF characters when editing configuration files. An attacker could possibly use this issue to execute arbitrary code. (CVE-2025-48384)

David Leadbeater discovered that Git incorrectly handled verification when fetching remote Git repositories. An attacker could possibly use this issue to perform protocol injection, leading to arbitrary code execution. This issue only affected Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04. (CVE-2025-48385)

David Leadbeater discovered that Git incorrectly handled memory with the wincred credential helper. An attacker could possibly use this issue to cause a denial of service. (CVE-2025-48386)

  "details": "USN-7626-1 fixed vulnerabilities in Git. The update introduced a regression\nin gitk and git-gui. This update reverts the corresponding fixes for\nCVE-2025-27613 and CVE-2025-46835 pending further investigation.\n\nWe apologize for the inconvenience.\n\nOriginal advisory details:\n\n Avi Halachmi discovered that Git incorrectly managed file modification\n constraints with Gitk. An attacker could possibly use this issue to create\n or write to arbitrary files on the system. (CVE-2025-27613)\n \n Avi Halachmi discovered that Git incorrectly handled arguments when\n invoking the Gitk utility. If a user were tricked into cloning a malicious\n Git repository, an attacker could possibly use this issue to run arbitrary\n commands. This issue only affected Ubuntu 24.04 LTS, Ubuntu 24.10, and\n Ubuntu 25.04. (CVE-2025-27614)\n \n Johannes Sixt discovered that Git incorrectly managed file modification\n constraints with Git GUI. If a user were tricked into editing a file in a\n malicious Git repository, an attacker could possibly use this issue to\n create or write to arbitrary files on the system. (CVE-2025-46835)\n \n David Leadbeater discovered that Git incorrectly stripped CRLF characters\n when editing configuration files. An attacker could possibly use this\n issue to execute arbitrary code. (CVE-2025-48384)\n \n David Leadbeater discovered that Git incorrectly handled verification when\n fetching remote Git repositories. An attacker could possibly use this\n issue to perform protocol injection, leading to arbitrary code execution.\n This issue only affected Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.04.\n (CVE-2025-48385)\n \n David Leadbeater discovered that Git incorrectly handled memory with the\n wincred credential helper. An attacker could possibly use this issue to\n cause a denial of service. (CVE-2025-48386)\n",
