CVE-2026-10758: CWE-190: Integer Overflow or Wraparound in Esri Lerc
CVE-2026-10758 is a high severity vulnerability in Esri LERC, an open-source image/raster format library. It involves an integer overflow or wraparound leading to a heap-based out-of-bounds write. This flaw affects LERC versions 0 through 4.1.0. An unauthenticated remote attacker can exploit this by providing specially crafted imagery to cause the application using LERC to crash, resulting in denial of service. No confidentiality or integrity impact is indicated. No patch information is provided.
AI Analysis
Technical Summary
Esri LERC versions 0 through 4.1.0 contain an integer overflow vulnerability (CWE-190) that can cause a heap-based out-of-bounds write. This occurs when processing attacker-controlled image data, potentially crashing the application and causing denial of service. The vulnerability is remotely exploitable without authentication and requires no user interaction. The CVSS 3.1 base score is 7.5, reflecting high severity due to the network attack vector and complete denial of service impact. No information about a patch or vendor advisory is available in the provided data.
Potential Impact
Successful exploitation results in denial of service by crashing the application using the vulnerable LERC library. There is no impact on confidentiality or integrity according to the CVSS vector. The vulnerability can be triggered remotely by unauthenticated attackers supplying maliciously crafted imagery.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting or validating input imagery processed by LERC to reduce risk of exploitation. Monitor vendor channels for updates and apply official patches once released.
