The vulnerability of the set_data() function in the src/libgit2/transports/smart_pkt.c file, which implements Git methods in the C language, allows a hacker to cause a service failure.

The vulnerability of the setdata function in the src/libgit2/transports/smartpkt.c file, which implements Git methods in C language, is related to insufficient validation of input data. Exploiting this vulnerability could allow an attacker to cause service failures...

CVE-2026-53584

A flaw was found in libgit2. This vulnerability allows a remote attacker to create directories outside of the intended repository working tree. By crafting a malicious repository that specifies traversal components in a submodule path, applications initializing the submodule can be tricked into...

libgit2: libgit2: Submodule path traversal allows arbitrary directory creation

A flaw was found in libgit2. This vulnerability allows a remote attacker to create directories outside of the intended repository working tree. By crafting a malicious repository that specifies traversal components in a submodule path, applications initializing the submodule can be tricked into...

libgit2: libgit2: Information disclosure via HTTP redirect allows credential leakage

A flaw was found in libgit2. The built-in HTTP transport component incorrectly handles offsite redirects, leading to the disclosure of sensitive information. An attacker controlling a trusted Git host or an open redirect on that host could exploit this by causing the library to send HTTP Basic...

libgit2: libgit2: Network attacker can intercept HTTPS connections via inverted IP SubjectAltName comparison

A flaw was found in libgit2, a C library for Git functionality. An inverted comparison in the OpenSSL backend's certificate verification logic, specifically when handling IP-literal hosts and certificate IP SubjectAltNames, allows a network attacker to intercept HTTPS connections. By presenting a...

Important: Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update

An update for Red Hat Hardened Images RPMs is now available. This update includes the following RPMs: libgit2: libgit2-1.9.7-1.hum1 aarch64, x8664 libgit2-devel-1.9.7-1.hum1 aarch64, x8664 libgit2-1.9.7-1.hum1.src src...

libgit2: libgit2: Denial of Service via Unbounded Memory Allocation

A flaw was found in libgit2. The gitdeltaapply function incorrectly trusts an attacker-controlled size value from a delta object header, which is used for memory allocation before proper validation of delta instructions. A remote attacker or local user can supply malicious pack data, for example,...

libgit2: libgit2: Denial of Service due to heap out-of-bounds read from malicious Git server

A flaw was found in libgit2. A fixed-size string comparison in the setdata function within transports/smartpkt.c does not adequately verify the size of a network packet buffer. A remote attacker, operating a malicious Git server, can send a specially crafted packet-line capability buffer. This ca...
