CVE-2023-41359

An issue was discovered in FRRouting FRR through 9.0. There is an out-of-bounds
read in bgp_attr_aigp_valid in bgpd/bgp_attr.c because there is no check for the
availability of two bytes during AIGP validation.

Comment 1 Cathy Hu 2023-08-29 08:35:52 UTC 
I think the issue was introduced with this commit in frr version 8.5: https://github.com/FRRouting/frr/commit/97a52c82a569f4a2ba792fbd734f5e635a057e6f

We dont have 8.5 yet, so tracking as not affected:
- SUSE:SLE-11-SP1:Update/quagga  0.99.15
- SUSE:SLE-12-SP2:Update/quagga  1.1.1  
- SUSE:SLE-15:Update/quagga      1.1.1
- SUSE:SLE-15-SP4:Update/quagga  1.1.1
 
- SUSE:SLE-15-SP3:Update/frr     7.4  
- SUSE:SLE-15-SP5:Update/frr     8.4    

Please let me know in case you have concerns, thanks :)
