Red Hat Security Advisory: libsoup security update
Two security vulnerabilities have been identified in the libsoup HTTP client and server library used in GNOME, affecting Red Hat Enterprise Linux 9. 4 Extended Update Support and related variants. The first vulnerability (CVE-2026-0719) involves a signed to unsigned conversion error that leads to a stack-based buffer overflow during NTLM authentication. The second vulnerability (CVE-2026-1761) is a stack-based buffer overflow in multipart HTTP response parsing. Red Hat has issued an important security advisory with updated libsoup packages addressing these issues.
AI Analysis
Technical Summary
The libsoup library, which provides HTTP client and server functionality for GNOME, contains two security flaws leading to stack-based buffer overflows. CVE-2026-0719 arises from a signed to unsigned conversion error in NTLM authentication code, while CVE-2026-1761 is due to improper handling of multipart HTTP response parsing. Both vulnerabilities can cause memory corruption. Red Hat has released updated libsoup packages for multiple architectures and variants of Red Hat Enterprise Linux 9.4 Extended Update Support to remediate these issues.
Potential Impact
Successful exploitation of these vulnerabilities could lead to stack-based buffer overflows, potentially allowing an attacker to execute arbitrary code or cause denial of service. The advisory rates the security impact as Important (high severity). There are no known exploits in the wild at the time of the advisory.
Mitigation Recommendations
Red Hat has released updated libsoup packages that fix these vulnerabilities. Users of Red Hat Enterprise Linux 9.4 Extended Update Support and related variants should apply the security update as detailed in Red Hat advisory RHSA-2026:2007 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official update.
