Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4003-1 advisory.

- CVE-2026-59184: invalid heap pointer, causing out-of-bounds or use-after-free writes (bsc#1276849).
- CVE-2026-59186: On ILP32, the Array2D<Rgba> tile-conversion buffer size calculation overflows, allocates a much smaller heap buffer, and tile decode writes past that allocation (bsc#1276850).
- CVE-2026-59189: API can return an out-of-bounds pointer when a deep image has a non-zero dataWindow origin, resulting in a heap out-of-bounds read and crash, with potential information disclosure under a controlled heap layout (bsc#1276855).
- CVE-2026-59981: an attacker-controlled deep EXR file can access sample counts through row() performs an out-of-bounds read, which can crash the process or, under a controlled heap layout, return adjacent heap memory as sample-count values (bsc#1276862).
- CVE-2026-59982: an out-of-bounds pointer from TypedDeepImageChannel::row() when a crafted deep EXR has a nonzero dataWindow origin (bsc#1276853).
- CVE-2026-61555: crashing occurs when Imf::GetChannelsInMultiPartFile() processes a crafted EXR with an empty multiView header attribute and Imf::viewFromChannelName() indexes the empty vector for a dotless channel name (bsc#1276859).
- CVE-2026-68515: The utility allocates sampled channel storage using a truncated union_width / xSampling, then reads the sampled input through a Slice based on the misaligned union window, producing a heap out-of-bounds write (bsc#1276848).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected libIlmImf-2_2-23, libIlmImfUtil-2_2-23 and / or openexr-devel packages.
