CVSS: 7.1EPSS: 0%CPEs: 4EXPL: 0CVE-2021-29390 – libjpeg-turbo: heap-buffer-overflow vulnerability in decompress_smooth_data in jdcoefct.c
https://notcve.org/view.php?id=CVE-2021-29390
libjpeg-turbo version 2.0.90 has a heap-based buffer over-read (2 bytes) in decompress_smooth_data in jdcoefct.c. libjpeg-turbo versión 2.0.90 tiene una sobrelectura del búfer (2 bytes) en decompress_smooth_data en jdcoefct.c. A heap buffer over-read flaw was found in libjpeg-turbo. For certain types of smoothed jpeg images, the decompress_smooth_data() function may improperly enter a condition statement that leads to heap memory read of uninitialized data, which may cause an application crash or loss of confidentiality. • https://bugzilla.redhat.com/show_bug.cgi?id=1943797 https://github.com/libjpeg-turbo/libjpeg-turbo/blob/4e52b66f342a803d3b8099b79607e3158d3a241c/jdcoefct.c#L595 https://github.com/libjpeg-turbo/libjpeg-turbo/commits/main/jdcoefct.c https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/27NR3KG553CG6LGPMP6SHWEVHTYPL6RC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6T655QF7CQ3DYAMPFV7IECQYGDEUIVVT https://lists.fedoraproject.org/archives/list/package-announce&# • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-46822 – libjpeg-turbo: heap buffer overflow in get_word_rgb_row() in rdppm.c
https://notcve.org/view.php?id=CVE-2021-46822
The PPM reader in libjpeg-turbo through 2.0.90 mishandles use of tjLoadImage for loading a 16-bit binary PPM file into a grayscale buffer and loading a 16-bit binary PGM file into an RGB buffer. This is related to a heap-based buffer overflow in the get_word_rgb_row function in rdppm.c. El lector PPM en libjpeg-turbo versiones hasta 2.0.90, maneja inapropiadamente el uso de tjLoadImage para cargar un archivo PPM binario de 16 bits en un búfer de escala de grises y cargar un archivo PGM binario de 16 bits en un búfer RGB. Esto está relacionado con un desbordamiento del búfer en la región heap de la memoria en la función get_word_rgb_row en rdppm.c A heap-based buffer overflow vulnerability was found in libjpeg-turbo in the get_word_rgb_row() function in rdppm.c. The flaw occurs when the PPM reader in libjpeg-turbo mishandles use of the tjLoadImage() function for loading a 16-bit binary PPM file into a grayscale uncompressed image buffer and then loading a 16-bit binary PGM file into an RGB uncompressed image buffer. • https://exchange.xforce.ibmcloud.com/vulnerabilities/221567 https://github.com/libjpeg-turbo/libjpeg-turbo/commit/f35fd27ec641c42d6b115bfa595e483ec58188d2 https://access.redhat.com/security/cve/CVE-2021-46822 https://bugzilla.redhat.com/show_bug.cgi?id=2100044 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
