AI Analysis
Technical Summary
CVE-2026-50811 is an out-of-bounds read vulnerability in the FreeType library's TT_Get_Var_Design implementation. This flaw allows remote attackers to trigger a denial of service or possibly read sensitive memory by supplying a crafted font file. The vulnerability is classified under CWE-125 (Out-of-bounds Read). Red Hat has issued updated RPMs for FreeType (version 2.14.3-1.2.hum1) for affected architectures (aarch64, x86_64) as part of the Red Hat Hardened Images security update. The vulnerability has a Red Hat CVSS v3.1 base score of 7.1, indicating high severity, with network attack vector, low complexity, no privileges required, and potential confidentiality and availability impacts.
Potential Impact
An attacker can remotely supply a malicious font file to trigger an out-of-bounds read in FreeType, potentially causing a denial of service (application crash) or leaking sensitive information such as cryptographic keys or memory addresses. This information could be used to bypass protection mechanisms like ASLR and facilitate further attacks. The vulnerability affects confidentiality and availability but not integrity.
Mitigation Recommendations
Red Hat has released updated FreeType RPM packages (version 2.14.3-1.2.hum1) that fix this vulnerability. Users of Red Hat Hardened Images should apply these updates promptly. No other mitigations are specified by the vendor advisory. Patch status is confirmed as fixed in the updated packages.
