CVE-2026-109350

The gitoxide gix-pack component, in versions before 0.75.0 , is vulnerable to a Denial of Service (DoS) condition. The root cause lies in how the software handles crafted thin-pack OFS_DELTA entries during fetch operations. Specifically, if a remote server serves a thin pack where an OFS_DELTA 's...

CVE-2026-109350 Gitoxide gix-pack before 0.75.0 Denial of Service via OFS_DELTA Base Distance

Gitoxide gix-pack before 0.75.0 contains a denial of service vulnerability that allows malicious remotes to crash fetch operations by sending crafted thin-pack OFSDELTA entries. Attackers can serve a thin pack with a REFDELTA referencing an existing object followed by an OFSDELTA whose basedistan...

CVE-2026-109351 Gitoxide gix-pack before 0.75.0 Denial of Service via Pack Header Object Count

Gitoxide gix-pack before 0.75.0 contains an uncontrolled memory allocation vulnerability that allows remote attackers to abort the process by supplying a huge pack-header object count. Malicious remotes can serve a 12-byte pack header claiming 0xFFFFFFFF objects, forcing Tree::withcapacity to...
