Bug 810541 – <media-libs/openexr-{2.5.7,3.1.1}: OOB read (CVE-2021-3605)

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description John Helmert III 2021-08-26 21:22:11 UTC]

CVE-2021-3605:

There's a flaw in OpenEXR's rleUncompress functionality in versions prior to 3.0.5. An attacker who is able to submit a crafted file to an application linked with OpenEXR could cause an out-of-bounds read. The greatest risk from this flaw is to application availability.

[Comment 1 John Helmert III 2021-08-26 21:24:04 UTC]

I can see the patch is in 3.1.1, what about 2.5.x?

[Comment 2 Bernd 2021-08-26 21:43:17 UTC]

Should be in 2.5.7 as well, if I'm not wrong, see [1][2][3]. [3] mentions PR 1036.
