CVE-2024-12085: Use of Uninitialized Resource
A flaw was found in rsync which could be triggered when rsync compares file checksums. This flaw allows an attacker to manipulate the checksum length (s2length) to cause a comparison between a checksum and uninitialized memory and leak one byte of uninitialized stack data at a time.
AI Analysis
Technical Summary
The vulnerability in rsync (CVE-2024-12085) arises from the use of uninitialized memory during checksum comparison, which can be triggered by manipulating the checksum length (s2length). This causes rsync to compare a checksum against uninitialized stack data, leaking one byte of memory per operation. The issue affects multiple architectures and versions of Red Hat Enterprise Linux 9 and 10. Red Hat has released patched versions of rsync to address this flaw, as detailed in their security advisories RHSA-2025:0324 and RHBA-2025:6470.
Potential Impact
Successful exploitation of this vulnerability can lead to information disclosure by leaking uninitialized stack memory bytes. The CVSS score of 7.5 reflects a high confidentiality impact with no impact on integrity or availability. There are no reports of active exploitation in the wild. The vulnerability affects rsync versions shipped with Red Hat Enterprise Linux 9 and 10 across multiple architectures.
Mitigation Recommendations
Red Hat has released official security updates for rsync in Red Hat Enterprise Linux 9 and 10 that fix this vulnerability. Users should apply these updates promptly by following the instructions in Red Hat advisory articles (https://access.redhat.com/articles/11258). No additional mitigation is required beyond applying the vendor-provided patches.
