Libultrahdr: Heap-buffer-overflow in ultrahdr::IccHelper::readIccColorGamut
A heap-buffer-overflow vulnerability exists in libultrahdr within the ultrahdr::IccHelper::readIccColorGamut function. This issue was reported by OSS-Fuzz and causes a read overflow on the heap during ICC color gamut processing. The vulnerability affects multiple specific versions of libultrahdr, including 1.3.1, 1.4.0, 1.5.0, 1.5.1, and versions at or after commit cff53d31267fd8396ecf6bf03f212fc8387f5672. No official patch or remediation guidance is currently provided. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
The libultrahdr library contains a heap-buffer-overflow vulnerability in the function ultrahdr::IccHelper::readIccColorGamut, as reported by OSS-Fuzz. The overflow occurs when reading ICC color gamut data, leading to a heap read overflow. The crash state involves the functions ultrahdr::IccHelper::readIccColorGamut, ultrahdr::JpegR::decodeJPEGR, and uhdr_decode. Affected versions include 1.3.1, 1.4.0, 1.5.0, 1.5.1, and versions from commit cff53d31267fd8396ecf6bf03f212fc8387f5672 onward. No CVSS score or vendor advisory is available, and no patch links have been provided.
Potential Impact
This vulnerability can lead to a heap-buffer-overflow read, which may cause application crashes or potentially enable further exploitation depending on how the library is used. No confirmed exploits are known, so the immediate impact is limited to potential denial of service or memory corruption in applications using the affected libultrahdr versions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory or OSS-Fuzz reports for current remediation guidance. Until a fix is available, users should consider avoiding use of affected versions or apply any available updates once released.
