BSD Portsgiflib -- Buffer Overflow vulnerability
· CVE-2026-26740 · VuXML entry
https://github.com/zakkanijia/POC/blob/main/giflib/giftool/giflib_giftool_gce_len_heap_oobwrite_disclosure.md reports: Buffer Overflow vulnerability in giflib v.5.2.2 allows a remote attacker to cause a denial of service via the EGifGCBToExtension overwriting an existing Graphic Control Extension block without validating its allocated size.
Affected versions
- giflib < 6.1.3
By system
2 still vulnerable, 1 fixed. Where VuXML applies (FreeBSD, DragonFly, FreeBSD's derivatives) a port is vulnerable while its version is in a range; pkgsrc says itself whether it lists a CVE of this advisory; OpenBSD and MidnightBSD keep no list this site reads, so their row is only an estimate: FreeBSD's ranges applied to upstream's version.
| System | Port | Version | State | Fixed |
|---|---|---|---|---|
| DragonFly | graphics/giflib | 5.2.2 | vulnerable since 2026-07-21 | |
| OpenBSD | graphics/giflib | 6.1.3p0 | out of range, by version | |
| NetBSD | graphics/giflib | 6.1.3 | listed since 2026-07-21 | |
| MidnightBSD | graphics/giflib | 5.2.2_1 | in range, by version | |
| FreeBSD | graphics/giflib | 6.1.3 | fixed | (3 days after) |
