CVE-2007-5268

Publication date 8 October 2007

Last updated 24 July 2024

Ubuntu priority

Negligible

Why this priority?

pngrtran.c in libpng before 1.0.29 and 1.2.x before 1.2.21 use (1) logical instead of bitwise operations and (2) incorrect comparisons, which might allow remote attackers to cause a denial of service (crash) via a crafted PNG image.

Notes

jdstrand

given medium because of wide install base bug (1) is said to have been introduced in 1.2.19. Looking at pngrtran.c in 1.2.8 and 1.2.15 (as included in Ubuntu), the vulnerable code is not present bug (2) still applies to 1.2.15, but not 1.2.8 reducing to negligible as pngset.c change should not do anything
