CVE-2026-47121 Sparkle: Binary delta apply intermediate-symlink traversal in malicious .delta

Sparkle is a software update framework for macOS. Prior to version 2.9.2, Autoupdate/SUBinaryDeltaApply.m enforces relativePath.pathComponents containsObject:@".." and rejects writes whose immediate parent directory IS itself a symbolic link, but does not detect symlinks deeper in the relative...

CVE-2026-47121

Sparkle vulnerability CVE-2026-47121 (affecting macOS AutoUpdate) arises from a defense-in-depth gap in delta application. An archive item can create a symlink in the destination tree and a subsequent file write may traverse the symlink path, allowing writes outside the intended destination when ...

The vulnerability of the `git_delta_apply` function in the `delta.c` component of the Git methods implementation in the C language, Libgit2. This vulnerability allows an attacker to access confidential data and also trigger a denial-of-service attack.

The vulnerability of the gitdeltaapply function in the delta.c component of the Git methods implementation in the C language, part of Libgit2, relates to reading data beyond the allowable buffer size. Exploiting this vulnerability allows an attacker to gain access to confidential data and also...

SUSE CVE-2018-10887

A flaw was found in libgit2 before version 0.27.3. It has been discovered that an unexpected sign extension in gitdeltaapply function in delta.c file may lead to an integer overflow which in turn leads to an out of bound read, allowing to read before the base object. An attacker may use this flaw...

libgit2 Denial of Service Vulnerability (CNVD-2018-20567)

libgit2 is a portable, C implementation of the Git core development kit . A security vulnerability exists in libgit2 versions prior to 0.27.3, which stems from a lack of security detection in the 'gitdeltaapply' function of the delta.c file. An attacker can exploit this vulnerability to cause a...

libgit2 integer overflow vulnerability (CNVD-2019-06643)

libgit2 is a portable, C implementation of the Git core development kit . An integer overflow vulnerability exists in the 'gitdeltaapply' function of the delta.c file in versions of libgit2 prior to 0.27.3, which can be exploited by an attacker to disclose a memory address or cause a denial of...
